lol the point is not to help you sleep.
in hospitals when you have an allergic reaction they give you a high dose of benedryl usually IV. but sometimes they gave it to me oraly as well.I am allergic to everything and its how I handle reactions.
instead of taking 2-4 benedryls if you have a tylonel PM or sleep aid with the same active ingrediant laying around you can take one of them and its the same thing.
and if 3 of them knock you out then 1 would make you drowsy but it will give you the antihistimine properities you are looking for.
also tlyenol PM will give you the antihistimine and also tylenol to break a fever or that "heat" you are feeling,and any sorness you may have.
Just giving you a couple more options of doing the same damn things really.
AND YES stop Poking at it.
STOP IT. youll be alright just relax a bit watch some tv or something.
