I'll speak as a recovering alcoholic (20 years) and what my experience was. I couldn't have gotten sober on my own and owe my life to the support of other recovering alcoholics in AA. For the first six months or so, I focused on meetings, meetings, meetings and did things with other recovering alcoholics. Understand that it is very stressful to go from being a daily drinker to someone sober and it doesn't happen overnight. Basically you have to get used to life as a sober person and that takes time. Doing anything sober for the first time was challenging.
But once I was on my feet I found I didn't need to limit myself. I don't hang out in bars or with people who drink heavily but otherwise I went on picnics, saw friends for dinner, went to the movies, traveled. What helped was looking for new activities on
Meetup where I discovered I love to hike and be outdoors.
