I know that lack of sleep is a big problem in the comics industry.  Huge work loads plus short deadlines usually means that sleep gets compromised.  But sleep is important. 

Give this a read and see if any of the points listed here effect you.  My grandmother died of Alzheimer’s, it might be in my own blood, and every time I read an article about the health risks of losing sleep, it terrifies me to think that for every hour I work past midnight I might be erasing my own brain, and working myself into an early grave.  This is something that a lot of us really need to take seriously, because making our deadlines simply isn’t worth that.

Take care of yourselves.
