Everyone's experience will be different, but for me, when I slipped up with a six pack in December, it was about three days. But, when I drank vodka for two days, my withdrawals were as bad as when I had been drinking hard for years. I was taking better care of myself this time around, so my withdrawals didn't last as long, but I was still prepared to go to the hospital at any time. I had a bag packed sitting next to the door all week.
