I'm about 20 months post-mirena, and I'd say I'm about 98% better, but it's hard to be sure since I'm pregnant and don't have the ups and downs of a cycle right now. Things I've noticed that still happen occasionally to me are: I'll notice my heart beating faster than normal. I'll have a sudden headache on the left side of my head that goes away after 5 mins or so. My left eye will twitch for a few weeks, then suddenly go away. My left knee will hurt for about a half a day then go away. Currently the top of my left foot feels numb, it's been that way for a few days now. There are other random aches and pains that do the same thing, come and go. I'll notice only one thing maybe every week or two, it's never more than 1 thing at the same time (and strangely it all seems to be on my left side). It's almost like whatever silicone or toxins are left from the mirena are traveling around my body. The anxiety seems to completely have gone away, thank God. I hope I'll still feel this good after I have my baby. I'll post after a couple cycles.
