My biggest motivator is the fact that I know that I would probably end up dead within days or a couple of weeks of drinking again. I am convinced I would have a seizure as soon as I would go into withdrawal.
The last days of my drinking were so bad. I could no longer hold even water down in my stomach and my heart beat was racing AND, scariest of all, downing vodka no longer helped these symptoms. The smell of wine (my favorite drink) would make me nauseous, and so I had to hold my nose while drinking.
The alcohol stopped working for me and I know I will die if I ever go back.
