Well, I understand this as that it involved people too, and doing some things together.
So, if the alcohol was rather a facilitator, then the question is rather more about you wanting to keep your social circles/interests while just personally wanting to subtract alcohol from your consumption. Is that right?
After all, the options depend more on the people and the common thing that keeps you together, than alcohol by itself. Of course, your personal interests too.
Starting a whole new social circle is a whole new question.
Either way, it's doable, and quite liberating and money saving. Those 7-dollar pints and shots not drunk add up... well, should you not find a pricier substitute, hopefully healthier.
