My Dr. tried me on phentermine 15mg first for a month & then phentermine 30mg for a month and I only lost 1 pound in the 2 months. I actually felt more hungry on them. So now we are trying Belviq and I can't tell that I am taking anything. Has anyone had the same results? I don't want to spend the $ on the full prescription if it should have already started working. Thinking about trying Qsymia instead. Any comments are appreciated! I also saw that you are supposed to exercise with Belviq but I am in disability because of my back and hands so I can't do any kind of vigorous exercise. I just need an appetite suppressant, only need to loose 30-40 pounds.
