Phentermine
"*Update*  I'm 5'9, 29 yr, female, started at 266lbs. It's day 36, and I've lost about 16 pounds.  The only thing I experienced was dry mouth within the first week. Since then that has subsided, but now my feet and hands are tingly. It's not severe but enough to be annoying. I still feel great. No other side effects. Since taking it, I'm teaching myself to choose better foods and make smaller plates. Trying to establish good habits while it's easy to do so.  I haven't incorporated exercise in my routine yet, but I can't wait to see results when I do!  Still moving forward with it."
