LOL - love the name GreyGoose. Vodka was my beverage of choice - in fact, I used to joke that the Soviet economy collapsed when I gave up Stoli.
I drank for 20 years, and I experienced withdrawal within 24 hours of my last drink. It was tough - and it was Labor Day weekend, doing double shift in a restaurant. I felt like I was about 10 feet tall, made of straw, and someone was going to just breathe on me and I would shatter.
You've definitely passed the critical point for physical withdrawal. The rest isn't exactly a free ride on a pink duck - but it beats the heck out of the alternative. Stick around - you'll be rocketed into a new dimension!
My worst day sober is better than my best day drunk.
