TakaWould "after/before+negation," such as "after I don't smoke," would work fine?
Not in general. The negative does not mark a point in time, which is required after "before" or "after".
e.g.
Before I stopped smoking, I had a persistent cough.
After I stopped smoking, the cough went away.
There are few very odd cases, for example.
They were engaged for a very long time. They got married after I don't know how many years.

"After + negative" is not used in English. "Before + negative" is sometimes used in a threatening kind of way, for example:
Mom to child: "You'd better be good before I don't take you for ice cream."
"You'd better study before you don't pass your final exams."
That is not good English.
"You'd better be good
before I don'tor I won't take you to getforice cream."That is not good English.
"You'd better study or you won't
before you don'tpass your final exams."OK. Thanks, AS!
