What is your experience with more sleep vs little sleep? And how did you acquire the more and how did you acquire the little?

For 13-1/2 months I worked from 6:00 AM-11:30 PM, 7 days per week, no holidays or days off but it was 5 days on and 1 day off. During that time I averaged 3-1/2 to 4 hours of sleep a night. It took everything I had to maintain that schedule and there were days that when I left the office I could not drive due to exhaustion and would have to get a hotel.

I can comfortably get by on 5 hours sleep a night but anything less takes a toll and I will eventually sleep in.

Sleeping more is easy if you have the time to do so.
