A couple of times in the last few weeks, I've awoken suddenly from sleep trying to catch my breath. More than likely Sleep Apnea related. (currently waiting to sort that out.)

But I find myself remembering the OP by Doc on the guy who had the Heart Attack and thought he was visiting Hell..

Although I didn't feel like I was dying, waking up gasping for air will put a scare in you for a while. Makes you very very cautions about going back to sleep.. It takes me to a whole other fear level. A level that brings into light just how fragile life is and how quickly/easily we could slip from it...

Anyhow, I came back to read Doc's post again, truly nerve straightening stuff on page 1...
