Actually, I am doing so much better now. It is a night and day difference. I don't think I realized how bad off I was until I remembered what it is like to feel normal again.
I am not having any of my symptoms anymore except for insomnia, which may be linked more to stress than the Mirena itself. I tend to take OTC sleeping pills for two weeks leading up to my period.
The only real difference I have now is that I have much more noticeable PMS than before. A couple of days before my period begins I can be a scary monster to be around. Otherwise, I feel great and am doing 99% better than with the Mirena in.
