birth control
"I was on Loestrin 24 for over three years and it worked wonderfully with my period; after about two years my period was so light that I rarely even got one which was awesome. I also didn't experience any change in my sex drive. However, I accidentally went off of it about five months ago (due to a change in insurance and I couldn't afford it) and after about 3 weeks of being off of it I dropped ten pounds (which, while I was on the pill, was never able to accomplish no matter how hard I dieted) and found myself in a much more stable and elevated mood. I realized after the fact that, although the pill was great for doing what it was supposed to, it made me gain a ton of weight and I was consistently mildly depressed."
