ParaGuard?!

Sie
I'm currently on the Depo Shot, but I'm thinking about switching to something without hormones. The shot has just messed with my moods..& almost costed me my relationship. I've heard good things about the ParaGaurd IUD, but everything I've read people say they almost passed out from insertion. I just need some input on how you guys have reacted to it, and if the pain is really that bad.
