Phentermine
"Update so I started taking this on May 19th, 5ft tall and 250 pounds. I felt dizzy my first three days and ate very little.  I try to eat less than 1200 calories a day. Some days I'm still hungry though. It hasn't even been a month and today I weigh 224. That's 26 pounds in 27 days almost a pound a day with no exercise. The results for me have been amazing. I do have trouble sleeping so I usually take the pill earlier in the morning. I take a whole one a day. I also have had severe dry mouth mainly the last 3 days but I'm also taking a water pill."
