WOW! I am so glad that I found this web site. I have had the Mirena in for almost 3 yrs. I thought I was crazy with the side effects. In the beginning I just kept telling myself to give it time. Well, again three years later I finally have come to terms with the fact the Mirena is just not for me. I did not notice a weight struggle. Depression seems to get worst. Mood signs are unbearable for myself let alone for my kids and hubby. When I told my doc he suggested depression meds! No thanks. Looking forward to removing the Mirena in February.
