OMG!! I thought it was just me going through the turmoil. My friends love mirena, but as for me I hate the little b!@#$. As with everyone else who has posted my side effects are the same. I had mirena placed in on December 2008 (7 mos ago). I have gained 22 pounds, cranky, no energy, and not 2 mention HEAVY SPORADIC PERIODS. In fact the first night after having mirena placed in my hubby and I had sex it scratched his penis. I'm getting it removed on June 17.
