We have to find our own way to do this. Babies and children learn how to comfort themselves, but we drinkers forget how to do it after a while. I know I did, my first and only recourse was the bottle, and I even let it push out some of my other tools so that booze could take their place.
It's taken me a few months to start to fill my time with things I used to enjoy so much, and this has helped to reduce the number of things that need special coping attention. For those, I try to take a distant view, to see if I can get some perspective on the situation. I also try to see if my assumptions that led me to react the way I did are true, and they usually are not. If you want to know what I am explaining poorly, look at Cognitive Behavioral Therapy (CBT).
