I could totally see myself reacting the same way. I am prone to be the kind of drinker who will never finish a night without making sure the bottle was done for. I was ridiculous and on a destructive path. Your reaction is normal because "normal" people dont have the same strange deep craving that we got when we drank, the craving to drink more and more and more and more. But the fact we remain sober is whats important, and its the fact that we arent normal with alcohol that we need to do this. You didn't drink the vodka so you did the right thing. It was just the little alcy inside trying to convince you to have some, he doesnt go away.
