I've noticed the same thing, PS. If my body isn't fully recharged, it's just... off. I feel woozy and sick to my stomach. I think it's just the body's reaction to not going through enough REM cycles to fix yesterday's woes. As for how to fix it... get enough sleep? Sometimes that's difficult and I don't have any suggestions for when you know you're not going to sleep enough. But you're not alone.

You see these shackles
Baby I’m your slave
I’ll let you whip me if I misbehave

Tie me to the bedpost

I like it rough
cause I'd rather feel pain than nothing at all
