The side effects of mirena are awful. I would have never imagined just how numerous and bothersome they were. Glad to know you had the mirena removed. I just wanted to share a post with you that gave me a lot of valuable information about how to overcome the numerous side effects. It talks about cleansing the body and getting back in hormonal balance. From what I've read, cleansing can have a big impact on symptom relief. The article can be found at detoxscientific.com/mirena-weight-gain/ if you're interested. It talks about all of the side effects, not just weight gain. Wishing you the best of luck.
