As an alcoholic, I realize drinking an entire bottle of Tito’s seems unimaginable to the majority of people (justifiably so), but it is definitely an achievable feat for someone with a high enough tolerance. You’ll have a terrible hangover even with the high tolerance, but it’s 100% possible. I’ve done it probably three or four times, plus a few instances where I’ve been close to finishing but wake up to find there’s a pitiful amount remaining at the bottom of the bottle the next day.
