Many of my hobbies required me to be sober - kayaking, roller blading, ice skating. The closest I come would be drinking wine while cooking. I have to eat, so I really could not avoid that activity.
I just drink juice or tea instead while I am cooking and stay focused on what I am doing.
I think for me it will be a lot harder when spring/summer time hits, and I want to sit in my yard. I spent a lot of nights out there drinking. I'm also not looking forward to patio season - that first really warm day of Spring is going to be a nasty trigger day for me. Giving up drinking is a lot easier in the winter while I am hibernating.
I've already started to think of ways to occupy myself once the warm weather hits to make sure I don't relapse. I've already put feelers out to some of my non-drinking friends to see if they want to form a roller blading club. I've also started investigating sailing lessons, since it is against the law to drink and operate a boat.
