Well here's my worst: I relapsed after having dropped my tolerance and the EMTs scraped me out of a ditch and took me to my job, although thank God I don't work in the ED. Apparently I said something to the effect of "just let me die" which wound up getting me a babysitter (suicidaldrunksitter?) and wound up having to talk to a pgy-2 who very clearly (and nervously) recognized me. Fortunately my hospital is relatively with it on the evidence-based-practice even in behavioral health so he knew to wait until I was sober again to do a full assessment, because that would've been a whole week down the drain in grippy sock jail.
IME it comes back quickly if you ease back in but if you just go out to the bar and knock back 6 shots at once like you used to the EMTs very much will be scraping you out of a ditch. That's how most experienced addicts OD, by not thinking about it and remembering to slow the fuck down with their dosing after holding together sobriety for a while.
