so i found out that the pill Phentermine which is a prescribed pill to lose weight is only only taken for a short period of time like 3-6 weeks. I’ve been taking it for two years and i really haven’t seen much of a difference on me. it did at the beginning but then it didn’t work. I do have a poor diet and i don’t exercise so thats a reason why the pill hasn’t worked. I was wondering how long it takes to get out of my system
