how many hours breathalyzer?!

Put yourself in a position to not worry about being tested. Wait an hour after your drink before heading home. If you drink more than one drink and will drive then add a hour an hour for each drink. So if you had three drinks 1HR + 2 Half = 2 hours waiting drinking water before you leave. This will keep the normal healthy person in the low BAC range. More time is even better for get yourself a ride.
Sorry but if it takes you hours to do a breath test you are doing it wrong.
It should take a few seconds, not hours
Well I assume that's what you are asking as your question is lacking detail
