Congratulations on a very tough decision. I've never fought the alcohol addiction, but have had close friends who became alcoholics and fought their demons, and I've dealt with allergy-addictive food issues. No real addiction is easy to beat, but the "one day at a time" and even "one minute at a time" approach really does make it easier.
I'd recommend that you add a lot of fresh, raw and cooked vegetables to your diet, especially things that support the liver, like beetroot (beets). The nutrients in those veggies will help your body's systems to handle the adjustments and detoxification issues that come with withdrawal, and make it easier to get through. You might not feel much like eating any of that "good stuff", but trust me --it IS what you need and WILL make the process easier.
Sweating in a sauna may help, too (regular or, perhaps even better, the far-infrared type).
Regular slow, deep breathing may help.
Get busy with something positive, something interesting and/or something that improves your life. Get that garage shelf cleaned off, or the floor swept, or the porch railings painted, or whatever. The more positive change you can make in your life and surroundings, the more it will uplift and motivate you to continue making other (and tougher) positive changes, like staying sober. Get your life going on "an upward spiral".
You are now a guy who USED TO drink, and no longer a drinker. Now you drink water and healthful stuff. Get used to it. See yourself that way, and the way you WANT to be, instead of the way you used to be. We tend to live up to our inner "self image", most of the time.
Get outdoors and get some fresh air. Spend some time in a park or in the mountains or at a lake or somewhere... where there isn't any alcohol, of course. Let nature "cleanse" your body, mind and spirit, and rejuvenate you.
Remind yourself of all the benefits of your new lifestyle. More energy. More productivity. Better relationships with loved ones. A "you" whom you can feel more proud of. A chance to save a lot of money you used to squander on alcohol, and can now squander on better stuff (like audio gear!

).
In fact, it would be a good idea to sit down and list out --by hand, with a pen-- every single benefit of staying sober: list every reason you can think of, and add to it whenever you think of something else to add, no matter how trivial some things may seem. Read over the list every morning when you wake up, and every night before you sleep, until it has really seeped deep into your psyche.
Try to avoid temptation. Get rid of any and all alcohol in your house. Stay away from the environments in which you used to drink. Avoid bars and old friends who will push you to have "just one" (Addiction LOVES company!). If all your friends were drinkers, go make some new friends who are not drinkers, and who will support you in your efforts to remain sober.
If you feel tempted to backslide, come here and ask for help -- even if no one is physically with you, you at least know you have a lot of AK friends around really rooting for you to succeed! Sometimes just taking time to do something (like posting on AK) is enough to get past a bout of temptation. Usually those weak moments of craving are transient.
GOOD LUCK! :thmbsp:
