Is alcohol really the only thing you know to relax? Or is that the alcoholic voice trying to trick you into believing that it's the only thing you know?
A 10 minute walk, a hot bath, reading a book for fun, playing with pets, journaling, and heck if I hate to admit this but sometimes just washing the dishes (no dishwasher) helps me relax. I also create "art" lol even if all I do with it is give it away. Maybe come up with a list of your own.
