i have a similar routine with a sprinkle of melatonine. i found that melatonine makes all the difference, but i also heard that it doesn't work at all for some people.
Melatonin works great when you're trying to adjust your bedtime to be much earlier than when your body is expecting.
http://www.google.com/patents/US5449683:
"the dose of melatonin administered ranges from 0.1 to 1.0 mg of melatonin"
The larger dosages supposedly have less risk of running afoul of the patent.
You may need to break up the pill yourself.
EDIT: That was supposed to be 0.3mg
