NyQuil backfire

When upon taking a small to moderate dose of NyQuil or other OTC sleep aids which contain antihistamine as an active ingredient the ingested pharmaceutical produces undesired side affects such as jitteriness and/or increased heart rate which counter the intended result of sleep.
There is no known cure, treatment is focused on achieving sleep. Common treatments include: large quantities of liquor/cheap beer, more of said pharm, marijuana, drugs...

backsies

1. The act of revenge.
2. To return to a previous state.

1. As in the game of punch buggy, one would say "punch buggy, no backsies!" If you are punched back, thats defying the rule of no backsies.
2. Guy: I fucked a stupid cunt now whenever I talk to her she thinks she's my girlfriend. Once you fuck a bitch, there's no backsies.
