I truly believe it is the Mirena... I had mine removed 21 days ago and I feel great! You are right that the doctors make you feel like you are crazy. Believe me your not!!! I also went to the doctor many more times that I have ever been in my life. All for them to tell me that it was all STRESS. I knew in my heart that it wasn't stress related because I am usually Happy Go Lucky - always look on the bright side. I was also feeling 90 years old. I still have a day here and there that I am moody and feel really tired. But for the most part I am getting more and more back to normal. As for your husband, ask him to be understanding and your sex drive will definately be back before you know it :) Just make sure he knows that you love him.
I am currently taking Nature Made Daily Supplement it is a combo of Vitamin D, Vitamin B-6, Folic Acid, and Vitamin B-12. It seems to give me some energy and I don't feel so foggy.
