Wow, Trish you explained exactly what happens to me occasionally, usually during dinner for some reason. My DH will say, "Get your hand out of your plate," and all of a sudden I am awake with my fingers full of spaghetti sauce

Or I just fall asleep...I wonder if it is some kind of seizure...oh well...
Anyway, Kitty, you should get it checked out...just wait til the budget crisis is passed so you make sure Medicare will still be paid for
