Ugh, I know how you feel. I have some weird cramping that was diagnosded as dysmennorhea and usually have to take 5 or 6 Advil for it and stay in bed all day passed the hell out. Unless you have already tried it and it hasn't done anything for you, I recommend trying depo provera. It's a shot only once every 3 months and you might have a light period for two weeks straight, but if you are anything like I was on it after that there should be no more period. The only thing you have to watch out for it to make sure you're getting more than enough calcium. Just talking about it makes me want to get back on that stuff.

Currently my antidepressants are actually helping lessen my problems in that department, but they do nothing for what I am supposed to be taking them for.
