so tired

I am so tired I can't sleep. Does this happen to other people? My muscles are all on the verge of collapse. Walking Giles a little while ago, I could barely make it up the slope of the parking lot. But when I lie down in bed, I can't fall asleep or even feel rested. It's like my brain is stuck in the ON position after I forced it to be awake all day following a scant few hours of sleep.

I am trying to rememdy the situation with some wine. Ah, alcohol, panacea for all bodily and mental ills.
