I know EXACTLY how you feel, I thought the same thing. Mirena IUD is not telling all the symptoms and complications that come with this thing. I had insominia, depression, horrible mood swings, severe back pain, and tons of other things. I told my doctor and she denied that it was the Mirena IUD which was a bunch of crap. I got the thing removed and I can sleep just fine now...I would love to help you or be involved in a class action suit. This product needs to be off the market, or more research needs to be done...they at least need to list the REAL side effects and not lie about them...
