I actually prefer later shifts, it apparently works with my natural sleep schedule. And the sleeping thing has been constant throughout my life. I meant that one of the reasons I can't sleep is because I can't shut my brain off. I've tried meditation, sleeping pills, natural sleep aids, warm milk, tea, aroma therapy... every now and then I'll have a brief period of time where I may sleep normal but it's random and seems to have no rhyme or reason. I've been to 3 different doctors about it... Nothing is wrong, physically. At least nothing they can do anything about. I am a light sleeper and I skip stages of sleep. Yet even though I'm a light sleeper, I'm a lucid dreamer... and my dreams are real in that I can taste, smell, feel, etc. It's weird.
Anyway... I'm trying not to worry about it too much. It's just in the back of my mind. Always there. As for techies, I live with 2 of them so it's a constant thing. And a work with several. Problem is the biggest techies there are DBs.
