Like the others said, be careful. If you get the shakes or if your blood pressure spikes, go to the ER.
The first 3-5 days are the hardest, and the worst of everything is over in 7-10.
If you are determined to do this yourself, then eat nutritious food, drink lots of water, and drink Gatorade too. Stay away from caffeine, but honey with herbal tea can help with the cravings. Be VERY careful.
Are you quitting completely? You didn't mention that. If you're having DTs you really need to go to the ER and get detoxed. Alcohol WD also plays with your BP. You could have a stroke. Doctors need to monitor you. As shmtty28 mentions, it's very dangerous if you're real toxic and you maintenance drink all the time. Also, look up your local AA hotline and talk to the person on the other end about exactly how you feel right now. They're right in your area and they might possibly be able to get you some local help quickly.
As for me, one day I decided I'm all done. I maintenance drank all the time. I didn't know too much about quitting at all. I had bad shakes for a few days when I quit, but I was 36 years old and was in really good shape. But I ended up going to AA and they took care of me. This was in 1982 and i've never had another drink since. I also quit valium and sleeping pills at the same time. Now, at my age, I don't think it would be as easy!
I wish you the best.
if it is so serious that you are physically sick go to the hospital!!!! alcohol withdrawl is the most dangerous to do alone, worse than most hardcore drugs. stay strong
