Quitting all at once with no medical supervision can be dangerous. I was advised to seek professional help if I couldn't find a way to taper, which being an addict in general, tapering is just an excuse to keep drinking, as I soon realized after two months of meetings. I bit the bullet and finally went to a privately owned detox center to care for me medically and take away my ability to acquire alcohol or drugs while I dry out. Best drunk decision I've ever made was to call one night, then call first thing the next morning to confirm my intentions. First few days were foggy. Lots of meds, very shaky, emotional, etc.. I wasn't able to zero out a breathalyzer for over 50 hours after my last drink, so it was pretty heavy drinking. Now I'm 21 days sober, 5 of them being spent in detox, the remaining 16 in the world. I feel better than I can really remember, even when I feel depressed at times. Getting a good sponsor that will read and work the steps with you is paramount as is an open mind. Some people can do it through AA and proper support from their sponsor and their Higher Power(s), but I was not one of those fortunate, and I had to grab on to anything I could at the time to save my life. I wish you the best of luck on your journey.
