WOW! I had no idea that all these things that are happening to to me could be related to Mirena!! I have gained aver 20lbs, I have no sex drive, sleepy all the time, ZERO patients. All this started after I got Mirena. I got Mirena on Jan. 19, 2009, and my life has went down hill from there. I catch myself crying for no reason,I go from sweet to bitch in ONE SECOND!!! MY lower back hurts all the time. I have tried to lose the weight but I can't. I joined the gym. I do pilates, kickboxing and body sculpting and still i have no results. I cramp almost everyday. It hurts to have sex. You name it , I am feeling it. I made an appoint for Wednesday the 8th, hopefully they remove it!!!!!!! I will keep ya'll updated. Any body have any answers to my problems until then.
