I quit cold turkey also. I had cut down some before then - I had gone from probably averaging a bottle to a bottle and a half of wine a day to not drinking every day, and drinking a little less overall, but it was still a lot, and it was probably somewhat dangerous for me to just stop. I had no idea at the time that it could be a problem. Thankfully it wasn't. I know better now, and if I were giving another alcoholic advice on quitting I'd always tell them to get medical help.
