birth control
"I've been on this pill for about 5 years and I'm writing this while mournfully staring at the end of my last pack - my insurance changed and it's no longer covered. Even in the beginning my symptoms were mild besides the usual spotting. My periods went from week-long, horribly heavy and painful, to barely noticeable, extremely light and only 2 days long. I've always had some mild anxiety/depression issues on and off so I can't say there was any change one way or the other there. I do suspect it fixed my sleep schedule though - I have always struggled SEVERELY with insomnia and around the time I went on this pill, I started having a normal human sleep schedule. I can't think of any other explanation - but I guess I'll find out for sure now."
