Okay, its not a direct reply to any one post, but I feel that this is the best place to post my "night shift regimen/recipe".
On a day when you have a night shift, do something physically demanding in the mid/late afternoon, then come home, hit the showers, get into your sleep gear, and sleep *hard* for 2-3 hours prior to your shift. Sleep 'in' to 12-2pm the following day, then repeat.
Real life example:
No night-shift/day off prior...
Sleep until 11am...
Wake up, coffee, small meal, check the e-mail, putz around your domicile...
Hit the gym/go swimming/play golf in the hot Florida sun/whatever from 3-5/5:30...
Go home and shower up. Curtains closed. Shut th'hell up. Sleep from 6pm until 9pm.
If you wake up before your designated 'wake up' alarm... don't move. Stay put with your eyes closed. Believe it or not, alpha-waves (awake, eyes closed) really do a bit of good for neurotransmitter regeneration.
Wake up, coffee, shower up, go to work.
Sleep from 7am-1 or 2 pm.... repeat.
Its not for everyone, but my "pro-nap" from 6-9pm really does me good.
