Valerian has helped me a lot in the past, also burn lavender or take hot baths with it in the water, that helps too... Kava is more for long term treatment in small doses, valerian is for immediate use. Also there is a company called energique that sells something called valericom thats an herbal mix, and Rescue Remedy - thats for sudden traumatic moments like if you got into a wreck or something you would take it immediatly. Cant remember what's in it but I know it helped me a lot too...
