Since god alone knows when I have been getting on average 2 - 4 hours of sleep a night. Occassionally I sleep for like 12 - 15 hours straight on a day off but rarely. I'm happy with the situation my body is coping mainly due to the experience of having Insomina for years. I can deal with 4 hours deep sleep a night and generally we're talking from the minute my head hits the pillow to the minute I wake up is deeep sleep.
