Shittly, unless my coma is drug induced.
I take a mixture of drugs and rotate them out so that I dont get immune to them.
I sleep on my stomach in a cold bedroom with the fan on, I have to have noise. The kids wake me up when they cough, but the drugs let me fall back asleep.
Often I wake up in the early hours and just think and think and think....it drives me nuts.
I only need 4 hours of uninterrupted sleep to function, but usually average 6
