Hi Tearose, Sorry things have been going soo crappy for you...I also have the sleep probs, my docs are plannning on putting me as an inpatient to see what's going on. I feel so much more irritable, etc. due to my horrible sleep patterns..My EP said he has an older women who has the sleep probs like I do (waking with tachy, sweats, etc.) and that they found numerous arousals (I'm guessing that means the adrenalin shoots up???), so it would be interesting to see what would be found with me. Most of the time it's the "hot flashes" that wake me up...Being 22 y/o I think I am too young to have those quite yet!! Anyhow, I hope you get soem sort of answer! Goodluck and keep us updated!
