Tim, its official. Your the smartest person i know. Sex ALWAYS worked for me. Though i think his real problem is that he works 2nd/3rd shift and his day is opposite most others'.
When I worked at a warehouse My shift was 5:30pm - 3:30am. By time I got home it was about 4am and for some reason I could NEVER fall right to sleep. I'd always stay up at least till 6 maybe later depending.
Ive been working my current 9-5 office job for the last year and a half and sometimes I still have a hard time actually going to bed before 1am. when I first started I would sometimes stay up till 2 even though i had to be at work at 9am. Best advice I could give is to give yourself an environment to sleep, really dark, really quiet, comfortable and relaxing. You dont want to do anything artificial like drink and/or take sleep drugs if you dont have to.
