It does work, but all it consists of is Acetaminophen & Diphenhydramine (Tylenol & Benadryl) ... Tylenol is tough on your kidneys & liver plus the brand name Tylenol PM stuff
is too expensive anyway, so if you don't have a headache & just want to sleep, go to Walgreens (or similar), snag a large package of generic Diphenhydramine & take 50mg of that by itself... if you DO have a headache, add 100omg generic Acetaminophen too. If price isn't an issue, just buy brand name Benadryl and use that instead, but taking Tylenol when your not in pain is a bad idea.
