This exact same thing happened to me- I had to have surgery to remove it. I actually let my Dr put in another while I was in surgery b/c they could place it better that way. It has been a little over a year and I'm having it taken out on Monday- can't wait. I have become the meanest person, moody, can't sleep, all of the side effects listed. Only 7 more days and I'll be done with it! Can't wait.
