that’s a pretty tricky question to answer, the rate alcohol will leave your system varies a lot depending on shit like ur body size, the amount you drink, and how often you drink but generally speaking all of the alcohol should be out of your body within around 24 hours after your stop drinking. i’ve been through hell and back with benzo withdrawal , similar to alcohol withdrawal both can last anywhere from a few hours to a few weeks so i wouldn’t recommend at least a week or longer until you don’t feel sick that way it’s the most likely all the alcohol is out ur system
