Nick Andreottola and his house guests woke up one morning in a Hamptons rental home feeling worse for wear -- bleary-eyed, heads aching, stomachs twisting. They were beyond hungover. 
 
 That's where the I.V. Doctor came in. For a few hundred dollars each, a nurse showed up with half a dozen I.V. bags and brought them back to life. 
 
 The I.V. Doctor, a service started in December by New York urologist Dr. Elliot Nadelson and his surgical resident son Adam, totes intravenous hydration and other medicine to help quell hangovers to ailing New Yorkers in luxe Hamptons beach homes, and apartments and offices throughout the city. 
 
 Dr. Adam Nadelson said the service has about 60 nurses in the city and 12 more in the Hamptons, who set clients up with about 200 ml of fluid, and any combination of anti-nausea, anti-heartburn and anti-inflammatory or headache medicine. The full cocktail of all the drugs, which Nadelson said is their most popular request, costs $249.

 While Nadelson said his clients range from European princesses to Olympic track stars, the majority of those who use his service are in finance. It helps when they're working long hours, entertaining clients late into the night and having to perform at a high level early the next morning. 
 
 "They're burning the candle at both ends and this helps them get back on their feet quickly," he said. 
 
 That's why Jon, a 31-year-old sales trader at a bank in New York who did not want his last name published, started calling the I.V. Doctor back in January. He was going to an event with clients for the Super Bowl and knew it was going to be a "big night," so he booked an appointment at his office the next morning at 8 a.m. 
 
 In a small, discrete conference room at his office, a nurse hooked him up to the I.V. bag while he checked emails for the next 40-or-so minutes, and she left in time for him to start his day. 
 
 "Look, it's not a miracle cure. There's nothing that really 100% gets rid of a hangover," he said. "But if you go in feeling like a 2, you come out a half-hour later feeling like a 7. That's a game changer." 
 
 Since then, Jon said he's had about a dozen appointments and recommended it to all of his friends. He now books an appointment in advance if he knows he's going out at night, so it's all set up for him at the office the next morning before a hangover can really set in.

 Adam Nadelson said the company is about more than just curing the over-served. They visit patients who have food poisoning or the flu, and athletes after big games or races. 
 
 But it's also about bringing in a new revenue stream. 
 
 "It's much harder to be a successful doctor today," he said, though his father still has three offices in New York. "You're starting to see family practitioners doing Botox on the side for money. This business has no overhead and is really catching on." 
 
 The Nadelsons aren't the first to climb up the hangover money tree. Hangover Heaven opened two years ago in Las Vegas, with a clinic open 24 hours a day, seven days a week. The services run from $129 to $239 in the clinic, but those who want a nurse to come to their hotel room will pay an extra $200 during business hours and $300 between 5 p.m. and 9 a.m.

 The Nadelsons aren't settling for just one city. They're expanding to Chicago this summer and are making a big social media play for potential clients in the Hamptons. 
 
 Andreottola and his Hamptons guests were satisfied. 
 
 "We're the work-hard, play-hard type and everyone said they felt replenished," he said. "Even some of the server girls we hired for a barbeque got it done and they all said they felt better." ||||| Melinda Sue Gordon / Warner Bros. 
 
 Todd Phillips’ deliberately offensive films have always courted controversy, but The Hangover Part III marks a tonal shift for his successful franchise. The movie is so aggressively nasty and barely funny that it feels as though Phillips is trying to cull his own Wolfpack down to only the most hardcore fans. The tagline on The Hangover Part III’s posters is “The end,” and there may be some wish fulfillment implied. The Hangover Part III gives off such a stench of creative decay that it hardly seems possible that even Phillips or his co-writers have any use for the movie themselves. If a movie can be self-loathing and self-destructive, it’s this one. 
 
 Even the impetus behind the journey, which does include a trip back to Las Vegas, the scene of the wickedly fun original, is bleak. Instead of a rollicking bachelor party enhanced by drugs, there’s a funeral, followed by an intervention. Alan (Zach Galifianakis) has been off his meds for six months when the movie begins. He is enticed to enter a treatment facility in Arizona by a promise that Phil (Bradley Cooper) and the rest of the Wolfpack — Stu (Ed Helms) and the guy who always gets left behind, Alan’s brother-in-law Doug (Justin Bartha) — will drive him there. Of course, the trip to Arizona is derailed — and the purpose of it completely forgotten — by an encounter with a drug-lord-type named Marshall (John Goodman) and his henchmen, including “Black Doug” from the first film. Marshall demands the guys find and bring him Mr. Chow (Ken Jeong), who double-crossed him around the time of the first Hangover.

 Alan’s specific mental-health issue has remained vague throughout the series, but whatever it is, it leads to some spectacularly dunderheaded and mean behavior. In his first scene in The Hangover Part III, Alan drives down the freeway pulling a wagon with a giraffe upright in it. It’s his new pet. The giraffe is obviously almost entirely computer-generated but still looks smart, soulful, friendly. It is decapitated by an overpass and the severed head plunges nose first into the windshield of an approaching car. The preview audience I was with seemed stunned into silence. Not by what had happened — the outcome is telegraphed from the beginning of the scene — but by a sort of larger why? Hardly anyone laughed. 
 
 What a contrast to the hilarity of the sight gag of that tiger in the bathroom of the Vegas hotel in the original movie. Even the abused, penis-nibbling monkey in The Hangover Part II seems slightly amusing in comparison. The dead giraffe served no purpose except to be grossly provocative. As oily pretty-boy Phil, Cooper demonstrated in the two earlier movies an uncanny ability to make almost any line funny, but here he’s reached his limits. It’s not Cooper’s fault, but the screenwriters’. No one, not Ernie Kovacs or Johnny Carson or Mel Brooks or even Chris Rock could make Phil’s line “Oh, come on, he killed a giraffe. Who gives a [expletive]?” funny. Other jokes that fail involve the cruel ends of a pair of guard dogs and some chickens trained for cockfighting and fueled on a diet of cocaine. They are variously shot, smothered, drugged, etc.

 The threat to the dogs even causes the cynical Phil to protest. “I didn’t know you worked for PETA,” says Mr. Chow (Jeong, reprising his role from the earlier films). “What a [expletive].” Maybe that line is supposed to make the audience feel chagrined about being such softies as well, but it isn’t witty enough to work. I suppose the dumb beasts give the steadily ridiculed character of Mr. Chow someone to look down on. Homophobia and underlying racism directed at Asians permeate this movie just as they did the others, with the ambiguously sexed Mr. Chow — he had or has a wife but, like Alan, can’t stop drooling over handsome Phil — subject to considerable verbal abuse. 
 
 Despite everything, Jeong has turned playing Mr. Chow into some strange art form. He gives the character radical style and confidence; no wonder Mr. Chow has become the central figure in The Hangover Part III. Phillips perhaps couldn’t make another movie without him (although, blessedly, that promise that this is “the end” does seem serious). The impish, outrageous mischief maker is the only force propelling the movie forward, unless you count the romantic subplot involving Galifianakis’ Alan and Melissa McCarthy’s pawn-shop proprietor, which is of a piece with the usual insulting mainstream grotesquerie involving the sexuality of the overweight. The Hangover Part III is such a misery that when Mr. Chow directs the Wolfpack to “stay low, like dog” it might as well be the film’s motto.

– If there's one thing everyone who's ever had a hangover can probably admit to, it's that they'll try just about anything to minimize the anguish. Now, thanks to The "IV Doctor," a service started in December by New York urologist Dr. Elliot Nadelson and his surgical resident son Adam, one's degree of suffering may be at least marginally reduced—for a price. Ailing partiers in NYC and the Hamptons (and, soon, Chicago) with the right kind of pocket change can for $249 have a nurse come to their homes or offices and administer 200ml of fluid by IV, plus a cocktail of drugs to combat nausea (Zofran), heartburn (Pepcid), and headache/inflammation (Toradol). That particular package, called "Revive," is the most popular, and recommended for those on their "deathbed." "Look, it's not a miracle cure ... but if you go in feeling like a 2, you come out a half-hour later feeling like a 7, that's a game changer," one repeat customer tells CNN Money. A reporter who tried the service for Thrillist—his prep included four martinis and an "indeterminate portion" of a whisky bottle—notes the advantages of the IV: a higher absorption rate, less peeing, and a quicker impact. He says he ended up "achieving a state of heightened alrightness ... a victory." Nadelson says his team has treated European princesses and Olympic track stars, but that his biggest client base works in finance, "burning the candle at both ends." This service isn't the first of its kind. Hangover Heaven opened two years ago in Las Vegas with a 24-hour clinic and nurses who will make hotel-room visits, and Miami and Atlanta are home to REVIV and Hydration Station, respectively. (Hungover? Don't blame it on this mixture.)
