I sleep terriibly. It got 'better', when i worked out i have a 'day', of around 32-36 hours. So, to people kon a regular 24 hour day, I'm tired at the wrong times and wide awake over aboit two of their sleep cycles. Damned annoying, as I've gone out when i should have stayed in - but everyone is out and awake, and viceversa. I've learned to say 'no' to invites I know I won't make. 8 hour working days, suck. For long creative bursts, it's great, though.
