Phentermine
"Had my first follow up today, been on Phentermine for 25 days and I'm down 19 lbs. Few side affects...cotton mouth, anxiety occasionally like twice a day for a brief period and constipation which has lead to hemorrhoids. But, given the success of 19 pounds in 25 days, they side effects are definitely not severe enough to stop. I thought about stopping if the weight wasn't coming off but it definitely is. I encourage you to use my fitness pal and track what you eat as well. I'm a 6'4 male that started at 322 pounds. All I eat is between 1200-1500 calories per day and feel great!"
