Today makes 8 days that I have been taking Phentermine.  I started on November 9, 2009 and I weighed 224 pounds.  I weighed yesterday and weighed 216.4!  I am so excited that I have lost weight already.  My goal is to reach 135 pounds and maintain that for the rest of my life.  I am doing low calorie-800-1000 calories a day along with Phentermine.  I have not had alot of side effects other than some itching, dry mouth, and constipation.  I go back to the diet doctor on Thursday for a weigh-in and to get a script for my Phentermine for a complete month.  I will be measured then and I will post pics and measurements.  I would love to find people in the same area as me that are trying to lose weight on Phentermine....would help to keep me motivated.  Good luck!
