What I hated about tapering, aside from the fact that it just didn't work for me, was that I thought about drinking all the time. It was as if cutting down just made the alcoholic beast in me angry and he would complain and whine until I relented and put the hammer all the way down. Worse, people around me would see me drinking responsibly which just reinforced my denial loop.
If you need medical help then so be it. You might as well do it at three in the morning on a work day with relatives in town because there is never a good time to quit. It is awful but it gets better. Much, much better.
