Could this be the "Mirena Crash" I've heard about?

In reading up about other ladies experiences with the Mirena as well as the effects after it was removed I came across many references to what is known as the "Mirena Crash".  This is a period of basically feeling exhausted, foggy brain, among other symptoms.  I brushed it off and thought, "ok...now that's reaching...really?  A mirena crash?".  Well, I am laughing no more because I think if it truly is a real phenomena that occurs after having it removed...I think I may be in the flux of it.

This past week I have been drop dead tired!  The last time I remember feeling this tired was when I had mono in college!  I am pushing through it, but if I sit down in a comfy chair or even worse, lay down on my bed....I fall straight asleep!  In addition, I've had headaches and can't sleep through the night because I keep having to go to the bathroom (you'd think I was pregnant!  I'm not...I pee'd on a stick...negative, phew).  The good news is I've lost 8 lbs since having the Mirena removed!  Another side effect, my vision has changed.  I got new glasses in February and they were perfect, but now my reading vision is not so clear (I do wear bifocals).  But I do know from my days as an ophthalmic tech and an optician that hormones will alter ones vision, so I need to wait until I am pretty sure things have leveled off before I go back in to get my eyes rechecked...just one more annoyance.

So I am curious to see how long I feel like this, and hopefully those last 10 lbs will decide to slide right on off as well.  The interesting thing about the weight gain to begin with....people kept telling me my ankles were swollen and my legs looked like I was retaining fluid.  The fact that these 8 lbs have come off so easily and with many trips to the bathroom makes me wonder how much was fluid retention.  Time will tell!
