Insomniac by night, zombie by day. That's me.
I'll go for days at a time with little or no sleep but when the tiredness does catch up, I have to call in at work sick just to catch up on the sleep when I can. OTOH, I'd rather not be operating the equipment when I'm that tired.
Marijuana -when I can get it- is the only thing I've found so far to manage or get some control over the insomnia. I'll get up and smoke some if I'm not asleep by midnight.
