"saturday july 18th i weighed in at my doctors office at 253 pounds. i started taking phentermine on monday 7/20 and today 7/24 i weighed in at 246lbs.  this pill has made it very easy for me to control my eating.  i stop when i&#039;m full and don&#039;t eat out of habit or bordem.  the only side effect i have experienced so far is slight headaches, but i have found that if i drink some water the tension goes away immediately. i have been taking it at the same time every morning right before breakfast to make it a routine and behavior modification.  i haven&#039;t started to exercise yet...that is next weeks mission but i am very excited to see the results and how this drug will get me on the right track to really change my life."
