We drink infrequently as we have (1) family members who have alcohol problems/addiction so we don't drink at family events and (2) alcohol is a budget buster.
DH and I enjoy sharing a bottle of red wine but if we do have it, it was a gift or I buy a $5 to $8 bottle. We do have beer on hand in the basement fridge but a 12 pack will last a month or more. We aren't huge fans of hard alcohol but have a bottle of tequila given as a gift so I do like to make a margarita every now and then on a Friday night.
It's crazy how big a mark-up on all drinks at restaurants! A glass of wine costs as much as a bottle so it really added up for both of us to have a drink. Plus, now when we go out to eat, it is usually a pizza place or Chinese and they don't have alcohol.
When I was younger (like 22-23), it wasn't a big deal to blow $25 on a Friday night on drinks at a bar. It makes me cringe to realize that I would spend $50 on a weekend just on alcohol. Young, single, working, different priorities.
