Dieting

Before I get into this, please know that I don't even like taking aspirin for a headache so taking diet pills to lose weight does not interest me at all.  Not to mention, I am pregnant and other than trying to eat healthier for my baby, dieting is not something I think about.  I know a few friends who are trying different things to help them lose weight and while I wish them all well, I wonder about some of their choices.  One thing in particular, is phytodren.  I've read reviews on it and it's supposed to be free of side effects but one of the things I always wonder when I hear about people taking diet pills is what will happen to their bodies and systems when they decide to stop taking them?  I just don't see how there can be absolutely no side effects when taking any kind of diet pill.  I just hope my friends do all the research they can before deciding to take this route.
