If you are looking for an OTC solution, I would recommend treatment with a medication that does not contain acetaminophen, as NyQuil
and Tylenol PM do. This will just cause unnecessary damage to your liver. Tylenol does make a sleep aid that does not actually contain acetaminophen, only diphenhydramine (Benadryl), which is what's making you sleepy when you take these meds. You can also find generic versions of Benadryl sleep aids at most drug stores.
