I've had trouble sleepign on & off over the yrs because I'm such a night owl & I do get really worked up about things when they are bothering me. An aspirin will usually help relax an "agitated brain". Sominex or any of the OTC diphenhydromine HCl's work pretty good for sleepign & aren't addictive. I used to pound Nyquil, benedryl, anythign to fall asleep. But then be useless in the morning. Stuff like melatonin, kava kava, etc. never did much for me except give me weird dreams for 3 hrs & then leave me staring at the ceiling the rest of the night.
