Will one shot of liquor a day build up my tolerance?
No, one shot a day will not build up a tolerance to liquor, unless you are taking shots of something decently strong. If you want to stick to one shot a day and build up a tolerance then I would recommend something like everclear. I personally can drink a half gallon of vodka in 2 hours and still walk straight, but that is from my “training.” Other than that I would say, just enjoy being able to feel the effects of the alcohol off of less, there is less of a chance of screwing up your guts that way.
