I have been taking Phentermine under the direction of my dr. now for about 2 years (on for 6 months off for 6 months). I started at 250 pounds and I'm now at 180. My goal is 135-140. I can not stress enough how very important it is to DRINK WATER while taking this medication. You CAN DIE if you don't. I ended up in the hospital for severe dehydration once, and that will never happen again. My hands locked up, my body started shaking, had a fever of 104, etc,.it's not fun. Side Effects I have experienced: Rapid Heartbeat Panic Attacks / Anxiety Nervousness Easily Irritated Sick at my stomach Constipation Constantly Thirsty Body/Hands Shake if you don't drink enough water The constant need to stretch every part of my body (this makes you want to get up and run around) Odd cravings for vegetables and dairy products Insomnia Abdominal Cramps (most likely caused by constipation) Diarrhea (usually only if I drink lots of orange juice or Starbucks) Feel like you are on speed (because you are)- you will clean your whole house if you take this stuff.
