Diet Supplements

I've been thinking about using diet supplements to curb my appetite and finally lose the extra pounds but I'm not sure if it's going to be worthwhile. I've heard of "horror" stories about people who've used supplements to lose weight, and then end up gaining more once they stopped taking them. And most of the ones I've seen so far have not been approved by the FDA so I'm really not sure how safe they are. I also don't believe the exaggerated weight loss claims accompanied by before and after pics. Yeah, I'm a cynic I know.
