i have been on mirena now for 3 yrs after having my son, since then i've had depression, insomnia, exessive tiredness, mood swings, but worst of all is no libido...(of course i'm not going to get pregnant if i never want to have sex!)
i think the side effects get worse with time....i'm seriously considering taking it out, the only positive thing i got out of it is that i don't get my periods....
