I have never known any full adult chronic binge drinkers that were successful at moderating and I know a few that have tried. I know a couple of people who binged in their early years (high school and college) that grew out of it and no longer binge drink (that I know of). I tried moderation a few times. I always stopped completely for months prior to trying to drink moderately rather than tapering. I always lapsed back into the old behavior and this time I plan to quit for good (just over 6 months in). If someone is unwilling to stop completely for a period of time, I have zero confidence in tapering being successful.
