Diet Pills......

The question comes to mind, every time you consider getting some sort of help for loosing weight.  Which are the most effective diet pills  and supplements, to take and how expensive are they?   You also want to know how long you must take them, how much to take, and what the effects will be on your health?  I often wonder why we should think this will last, once we stop doing the diet?  We will probably gain back the weight if we don't have a back diet to stabilize the weight loss.
