Phentermine
"Hi , I'm 40. 5-11 290 male when starting phentermine 37.5 mg. I figured I better post and help someone maybe not go through what I went through the 1st three days . Take on full stomach !!!!! I took this med on semi empty stomach the first 2 days and I thought I was going to come out of my skin it was horrible horrible feeling like I never felt !!!  I stopped my dose after day 2 and didn't wear off for another full day and slept 1hr in those 3 days !!!!! So day 4 I tried on a full stomach and no probs just the normal bad cotton mouth . I work swing shifts so I learned if your going to take this med take it as if it's not going to wear off for 16hrs. If you do this you'll be able to sleep if not good luck lol. lost 18 pounds this month"
