I used to get too ill to drink for a couple of days after a bender. Sick,, full of remorse determined not to drink again. But after a while I began to feel better, didn't really need to quit, forgot the misery, and off I went again.
I didn't seem to have the power to maintain the decision to not drink. I ended d up looking for the power in AA, and never drank again. Without a program I couldn't recover, and most programs or plans tried previously do not work with alcoholics of my type.
