"i was so excited to get on phentermine. i worked with a girl who was losing weight like crazy and asked her what she was doing and she told me she took this medicine. i was really nervous to take it because diet pills freak me out.  every kind i have ever taken has made me sick, jittery, and more hungry.  the very first day i took this pill i had no appetite, and all i wanted to do was drink water from having dry mouth, which is great because i usually hate water.  before i would have to eat at least every 4 hours or i would get sick, now i could go the whole day without eating!  the only thing is i have to make sure i at least eat 1 good meal or i get a migraine followed by some body aches, but then i can eat an apple and i&#039;m fine."
