I have to take progesterone because I have really bad periods if I don't take it but it has a really weird side effect. I have had a very high sex drive for years but progesterone makes it worse. Lots worse. I say "worse" and not "better" because I don't have a boyfriend so I wind up being driven completely crazy by certain scenes when I watch House and I had the dirtiest dreams last night. I hope I don't do something really idiotic.
