I think I am having the same side effects, i just described my differently. I feel like i am revved up and not sure why. I sometimes think it is anxiety, but I feel like I just ran and stopped suddenly and need to take a deep breath. How long did it take to taper off? I think I am going to have my adrenals looked at also. It was something that came up when I googled my symptoms, before I Knew it was Mirena. Thanks for your input!!!!
