In states of chronic stress why does the bodies receptors not become tolerant to things like norepinephrine, yet when taking medications it does?

@sb4 beware the caffeine and especially the Theobromine (which is like caffeine but works for hours or days) in cacao or dark chocolate.

Thanks @linusbert

I did not know about the Theobromine. It Might explain agitated feeling I get from dark chocolate. I'm very tolerant of caffeine so it had to be something else.
