Hangovers turn into waking up drunk at some point. For me, they were a reason to drink. Withdrawal is like a hangover that lasts for weeks. The whole time, you will want a drink.
My bottom was the realization that my alcoholism was a way of checking out of my life. Once I realized that, I just had to start doing other things and dealing with the problems I tried to drown.
When you are in the pit of addiction, the first things you need are positive alternatives to drinking. It could be AA but I went a different route. I am not a meticulous scheduler, but I had a rigid schedule for the first few months. I even planned out my free time. I put myself back out into the world, and found that I loved it and the people in it.
