About sleeping- I have been on Ambien for over 12 years. I am like you ( without the Ambien) I lay awake for hours, finally fall asleep and minutes later, boom I am awake and my heart beat is at almost 200 ( had to wear a monitor at night), after that I can't go back to sleep at all. So I settle for the Ambien, better than going crazy, because I have had a time where for over six months, I only got an average of 10 hours of sleep in a whole WEEK. Back then, I thought I was going to go insane ( which can happen if you don't get any sleep). My doctor thinks, that one of the ingreedients in the Ambien has a calming affect on my heart ( I have mitral valve prolapse).
Oh yeah, the cognition, CRS is what I call it, ( can't remember sh.. .), my husband finishes my sentences for me, because I can't think of a word.
Fatigue is a bummer, we all have it.
See, you are not alone. We are all with you on that.
I may have been dealt a bad hand, but at least I'm still playing with a full deck. ( most of the time anyway).
