since a pint of liquor is 16 ounces and there are 1.5 ounces in a shot there are approximately 10.5 shots in a pint. This means that according to normal metabolic rates (the liver degrads approx 1 ounce of alcohol per hr. in a healthy person, and at 80 proof (40% alcohol) @ 16 ounces this is equivalent to 6.4 ounces of alcohol, it will take about 6 and one half hours after you stop, to get sober. If you resume drinking at any time before that you have to calculate where you are in the time frame that you stopped (4 hrs, 3 hrs etc) and can calculate how much you degraded up to that point and start from there. For example if you drank a pint (6.4 ounces) and waited 3 hours that would be 6.4-3.0 = 3.4 and resumed with one shot 1.5 ounces at 40% you would be at 4.0 ounces within about 10 minutes and it would take another 4 hours to be at zero. 4 ounces on a breathalizer for a person of average build and who had eaten a farily good diet would blow about a .17 (way over the national limit of .08) so please be careful even after you stop: your blood picks up where it left off until it degrades to 0.00. You can use the figures above to extrapolate a quart, litre, etc. But remember it is not the quantity of fluid but rather the alcohol content in that fluid that dictates how drunk you are.
