Thanks Karl, sometimes when we are super busy I don't sleep normally. I know you sleep irregular hours yourself. I'm going to the store in a minute and stock up on some grub, maybe some shrimp (they are fresh here.) A nap will happen.
I have sleep apnea and sometimes don't get into the REM stage of sleep, where is where you get your rest... I usually wake up every 1 1/2 - 3 hours, so I take cat naps to try to get a little rest at a time... Sometimes I can sleep through the night when I'm wore-out tired....
