If you are trying to lose weight using weight loss pills just be careful and follow the instructions closely. Pay attention to your body while you are taking them. Think back to all the stuff that happened to people taking Redux and some other prescription medicines and don't assume that a product is safe for you just because it is an over the counter pill. Many of these have active ingrediants that can have various effects on your health. While most are safe for MOST people use caution in the beginning in case it doesn't react well to your body.
