My symptoms were just like yours. My doctor put me on prozac, but it just made me really tired all of the time and it did not seem to help, so I quit using it. My symptoms started about one year after I had it put it. It was around the same time my strings were lost. Come to find out, my Mirena acually broke. I had to have surgery to have it removed, but it was almost instant relief. My Mirena crash was nothing compared to how I felt with it in. I feel so much better now. I have had it out since Oct. I still have bad PMS, much worse then before the Mirena, but I feel really good the rest of the month. I have contacted a law firm that is looking into the Mirena. I just posted the information. Good luck!!
