Birth Control
"I went on this birth  control about 2 years ago and gradually gained about 20 pounds over the span of 4-6 months.  No matter what I did, I could not lose it.  My appetite had increased a lot and despite my efforts at the gym, I could not manage to get below 150 pounds.  I went off it a month ago and I have already lost 8 pounds and my appetite has gone back to normal. 

I never had my period at all on this pill and I never experienced mood swings due to this pill.  It reduced my breakouts, and it completely got rid of my cramping. I would not go on this pill again because of the weight gain but aside from that, it did what it was supposed to do. :)"
