I got mirena July 1, 2009 and I've had the most insane mood swings that my boyfriend hates being around me. I am not a person who gets stressed out easily or who overreacts but the last couple months I've been literally insane. I don't feel as if I can even control myself. I've been thinking about getting the no hormone IUC instead. I have gained weight but never thought that it could be because of mirena. Hopefully the IUC would help me to lose the weight I've put on. I like the worry free of no birth control pill but in the last 3 years I've never been this up and down with hormones. I would suggest, ladies think about the no hormones one, we may still have periods but none of these crazy side effects.
