ShadyBaby - be careful!!! If you've paid attention to the news lately, you know the dangers of ephedra containing products. YOW!!
If you are thinking of supplements, I have found a one-a-day multivitamin to be helpful against many cravings. Something about getting what my body needs helps me from wanting foods that contain it (ie. iron in red meat). Also, calcium has been found to be beneficial for weight loss. Not to mention as a young lady (I'm assuming) it is just a good idea. BTW, Vitamin C helps to have great skin.
Good Luck, I hope to see you around.
