Cryptkeeper,
I wish I had more answers for you, but still have many of my own! I have tried and been semi successful with taking walks in the evening, and also reconnecting to things I used to enjoy (although they were never alcohol free) , but its a start. For me woodworking as I used to build birdhouses and even built a blanket chest. Also (sort of a female thing mostly) but scrapbooking, but maybe you like to take pictures of things like nature, or go to museums, or still life...?
Also, I HAVE to comment on your "hard" hours as they are mine too! After I get off of work and have some free time, despite all the productive things I could be doing, it is hard to not drink and "chill out". I realized that although I think I am bored, there are many things I could be doing to be productive; read a boo or magazine article, Exercise, play a game (like solitare) do laundry, dishes, vacuum, dust, grocery shopping, taking a relaxing walk, bike riding, car ride with relaxing music, DO NOTHING FOR A CHANGE! MEditate, stretch, and despite all--Go TO Bed Early! I feel Amazing when I am in bed by 9 or 10 even if I don't fall asleep right away. Good luck to us all!
