It takes a while to enjoy doing things sober that you used to like to do drunk. For me, I never thought I'd enjoy playing in the yard and sitting around camp fires sober (though to be honest I really miss camp fires and drinking). I do enjoy those things now though. Then there are things you may never enjoy sober, so you will need to find new things. The list of things to do sober is endless, and is a matter of preference.
Exercise, movies, reading...playing with pets are a few that come to mind. Life is full of so many things to do, why tie it all to just doing things drunk?
