Detoxing is unpredictable. Some people can drink as much as you did and quit cold turkey without much issue, others have seizures and die. Sorry to be blunt, but my point is, it's always a good idea to have some sort of medical supervision or at the very least, someone who can be with you for a day or two at your home to make sure you're OK. Sometimes people feel ok for a day or so, and then suddenly start having problems. If I had known how dangerous it was when I quit cold turkey, I would not have done it alone. I didn't know. I was probably lucky. I never even considered tapering, but maybe it would work for you. Best idea is to find out what you can do about a medically-supervised detox.
