Its great to find a website about Mirena, but in my case as well as others its to late. I have had Mirena on for 4 month. I didnt realize that all the problems i was having was due to that. Just last night i could not fall asleep, it was 2 in the morning i was still awake. My libido is gone. and sex is very pain full . I have had headaches, dizzyness, itchy skin, leg cramps, and worst was heart palpatations. I ride bike and my heart does not beat as fast as when im sitting down and get up real fast. Im calling my doc, for advice....Good luck to all the women with Mirena
