Thankfully(?), I've reached a somewhat symbiotic relationship with my functional alcoholism. Drunk me does the laundry and empties the dishwasher, and sober me no longer nags drunk me for drinking so much.
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.
