I have had the same thing!!! The last 2 years my drinking got worse and I would be dizzy all of the time. I was always afraid of falling over. Then after quit drinking the dizziness was there for about 6 weeks. I think it definitely has everything to do with alcohol and nerves and blood sugar. So especially when I hadn't eaten (all i was eating was sugar when I quit) I would start to feel dizzy, then I would panic.. but then I would eat something and I felt a bit better in a few minutes.... but then I would still be worked up. I am over 3 months sober now and I don't have dizzy spells anymore. I hope you feel better. It's a very scary feeling.
