I was up to 15 ice type beers per day (5%+ alc). I switched to lite beer for the first week and kept the same consumption. Over the next several weeks, I reduced my consumption to 8, 6, and then 4 per day. I then had a few "off" days where I didn't drink at all, so I'd have 4, then 0, then 4, then 0. Eventually I was able to string together a few off days together, and soon after quit entirely for 2 years. By the time I was down to 4 or so beers per day I didn't even want them. I drank them to prevent any sudden withdrawals.
