[quote=DrJizzle;If you have 2 more drinks, you will be up to about a .1% BAC.. you would have to wait at least 2 more hours to be under what they consider the "legal limit".[/QUOTE]
I don't think the legal limit is the question. The question appears to be how to drink at all and not be violated while on probation as well as what type of testing will be done.
OP may be looking for one of the "magic drinks" which turn out to be not so magic after all.
Some States are tougher than others - Pennsylvania has NO tolerance if there is a "no drinking" provision in probation. People who used mouthwash have posted because they've been violated. NY is pretty much the same.
The answer to the kind of testing is: breathalyzer - if there is a problem or concern, a blood sample may be requested. "A blood test, however, can detect smaller amounts of alcohol and for longer periods. Small amounts of alcohol ingestion (one to three ounces) may still be detectable in the blood ten to twelve hours later—again, depending on the person. These figures are also for a non-habitual user, or the occasional drinker. A habitual drinker’s blood and internal organs will "store" the alcohol from successive drinking sessions, and it takes much longer—sometimes up to a week—to eliminate enough alcohol from the system to pass a blood alcohol screening. To metabolize alcohol out of your system, it must pass through your liver. A perfectly-functioning liver can metabolize an ounce of alcohol per hour—about one standard drink. Heavy drinkers, whose liver may be impaired, may metabolize much less than that, and would need to allow a much longer time before taking a blood alcohol test. You cannot speed up your liver’s functioning. This is why drinking large amounts quickly or chugging drinks can become fatal. What the liver can’t process, the blood must store, and alcohol poisoning can be the result. If planning for a blood alcohol test, it’s best not to drink any alcoholic drink for several hours to a day or two prior to the test date to give yourself the best chance for a clear test result."

What exactly are the terms of your probation?
