24/7/365 business also. 0000 to 0800 Tuesday through Saturday with the rare double, special detail, training or extra hours. I get 8 hrs of sleep 3-4 days a week, other work days 3-5. I have been known to sleep for 10-13 hrs straight on days off if I really lost out on sleep during the work week. Unfortunately, I've never been able to shake off the good(?) military training of getting 4 hours of sleep and go 36+ hours without sleep without a problem. Once awake, I'm awake.
