Phentermine
"I'm a 66-yr old female who started phentermine in August.  I lost 12lbs the first month, 6lbs the next month, then 4lbs, and this month only 1lb! Just read all the blogs & I'm going to stop the medicine for 3-4 days then start again.  At my last Dr. visit he upped my dosage to 2 tabs/day.  According to the blogs, I'm taking the tab at the right times of the day and in the right way.  I have an extremely active job and am on my feet 5-1/2 hr non-stop 5 days/week; however, am getting ready to start traveling with my husband in our RV so plan to start exercising by joining Curves/walking.  I'm thrilled with the way my appetite has decreased, don't think so much about food, and only eat fruits and veggies with regular meal at night.  Constipation is awful."
