I am so relieved after reading your posts.... I had the Mirena placed Nov. 2006.... I have an appt. to have it removed tomorrow! I would yank it out right now if I could ! ! ! I was really beginning to think there was "something" wrong with me ! Weight gain, DEPRESSION, mood swings, crippling lower back pain, no energy what so ever, loss of sex drive, the list goes on ! I can't wait to get this "THING" out of my body, it was the biggest mistake I ever made. My poor kids have been telling me that I'm not very happy . . .
