I've been on it for 6 months, very little appetite and lost 6 pounds. Makes me crazy when I see people losing 2 pounds a week! Historically I didn't have much of an appetite, but would "snack" at night. This stops me from snacking, I do everything I'm supposed to BUT not losing weight. 2.4 dose. Cash paying. The dr. keeps telling me to stick with it. Seems like a waste to me.
