Hi Keri
Hello, My name is Roy and I am an alcoholic of 24 years. I have put serious effort into quitting this year and have "slipped" also known as relapse twice pretty hard. It differs for each person but the last time I relapsed I drank for a little over a week and I went through the typical three day withdrawal and 6-7 day no-sleep thing all over again. He might have a couple of rough days but should be ok by Monday if he does not drink anymore this weekend.
Best of Luck and Nice to Meet You,
Roy
