DP and I met when we were part of a social circle that very much enjoyed a drink. We're still friends with those people, but it's definitely different to be out with them and not drinking/drinking moderately. Sometimes I miss it or miss the friendships, but mostly I'm glad not to feel so ropey in the morning.
We both cut back on the drinking because DP had no stop button. He could go weeks without a drink, but he couldn't go for "one" and popping out for a drink started impacting on things that were important to him next day.
I had less of a problem, but also knew I was drinking too much and was happy to cut back, feel better, save money and support him.
Neither of us has drunk much at all in months. We were away with friends last weekend and only drank one evening, which was fine, we had a great hangover free weekend. He does seem to have developed an ability to have just a couple.
He is away for a couple of days on business in a beautiful city where the liquid lunch is still a thing. He's sent me a lovely photo of a nice cafe and his beer. I don't think he'll drink to excess and I'm glad he's making the most of things, but I'm a bit offended that he doesn't want to relax with a drink with me, if he's going to have one...
