Stash Tea makes a tea called Sandman Tea, it works great. I have not been aboe to find it stores around me lately but it is available on their website. You can buy a box of 20 tea bags for the cost of O. bottle of Dream Water.
Celeste Tea Makes a tea called Sleepytime Tea. Also works great.
Both of these teas use natural herbs that induce relaxation and sleep. You don't know where these 'all natural' ingredients actually come from. I think you would be better off learning relaxation techniques, meditation, and the use of herbs instead of some concoction mixed up in a lab.
