I took phentermine 37.5mg for 3 years and lost 75 lbs. Another positive effect included being more alert during the day, feeling a slightly speedy effect as if I drank too much coffee, which helped me at school and work immensely. It was just great, I was back into my normal weight range. So I quit taking it for a year and then gained 55 lbs back.
I decided to take it again, returning to the same dr and same pharmacy for the same adipex 37.5mg. But now it has no effect on me whatsoever. No appetite supression, no alertness, nothing at all. It was like I was taking a placebo. Completely useless.
Has anyone else had this problem? How do you fix it? Do the effects come back in time? Or what? I’m thinking of trying Didrex now but nothing will work like Adipex.
Please help me, I just don’t understand why it doesn’t work anymore!
