So I'm trying to lose weight and lost 15 lbs but can't drop anymore weight. I was 235 lbs and now 220 lbs at 5'5. I've never been this heavy and it makes me feel like crap. I've been looking up different things to take that will help lose some weight and came across people talking about Phentermine worked great for them. Has anyone ever taken it? Did you lose weight and how much? How do I ask my doctor about getting prescribed it? Advice please and nothing negative.
