If it gets to the point I think I need to, I would give it a go.
This isn't the most cliche thing I could say (it is the cliche), but I can and do stop when I want to. Every few weeks, I'll go 2, 3, or 4 weeks without even a drop. Mostly just as a self-check to make sure I can. If I ever can't (yet to happen), then that's my notice that I have a real problem rather than one I joke about on the internet.
I do drink a lot and technically fall under textbook definition, but I don't hide bottles around the office, drink during the day, or feel like I have to have a drink to get through anything.
