I'm a very manic person who accidentally drank whiskey on a dessert recently (possibly =< a shot). How much time should it take for the alcohol effects to not affect my brain or thoughts, not even in a minimal, microscopic way? I know that it is probably out of the bloodstream, but does it alcohol effects linger on the central nervous system or something for more time?

please chemist and doctor bros. I could also use studies on such matters if you point me to one.

I know that it sounds ridiculous but for me its very important.
