I am like you at times not being able to sleep (a lot lately).

I have a toolbox. Sometimes nothing works but in the past I've tried the following:
Meds - Lunesta, Tylenol PM, Valium....I don't drink but if you drink enough you'll pass out.

Physical/Mental - hypnosis, meditation, music, (lots on youtube), rubbing your eyebrows for 2 minutes, orgasm, warm milk,
