Since we've done everything but answer your question, Atreides, let me share some usefull knowledge that I've figured out from fifteen years of shift work.
1. Go to bed early.
2. Stay away from naps.
3. Avoid things like coffee, carbonated beverages and such at least two hours before going to bed.
I would say that if you're sleeping through the buzzer of your alarm clock, switch to the radio. If that doesn't work, try cranking the volume on your ac. That works for me a lot.
