I had my Mirena taken out in May 2009, still feel foggy in my head and occasional dizziness... so afraid I will never feel like my old self again. I know feeling like this isn't normal and while I had mirena in I even sought the help of a neurologist because I had no idea why I was so dizzy. Could barely function and even now it effects my life so much. I am so upset still and can't explain to anyone how sick I still feel. Any responses are greatly appreciated, I am disgusted and distraught!
