birth control
"This shot is VERY effective for birth control, but the side effects are NOT worth it. I gained 17 pounds, had horrible mood swings, was constantly crying and moody, and I had the worst constant breakouts. I started it at 20 years old and had never had any acne in my life and had never had any problems with my weight. I immediately had bad side effects after starting the shot but decided to stick with it. I was on the shot for 9 months, and I thought that the side effects would go away, but they never did. It took me over a year and a half for my skin to get back to normal. If you try this shot and it does not work for you,  I do not recommend staying on the injections because it takes forever for the medication to leave your system."
