after mine came out, my headaches subsided and i only got them occasionally. and my Acne started clearing up immediately. the exhaustion i was having with it did go away immedietaly, i had so much energy just the very next day! it has now been two months since it came out. if it wasnt for the fact that i got pregnant a month afterwards and was now having a d&c wednesday, i would be feeling great. i know that the mirena had something to do with it, but no dr is going to believe me.
