Advice: How do you respond to "we should get together for drinks sometime"?

"Getting together for a couple drinks" has been something I've used to navigate that awkward meeting with someone new, that business contact you want to get a little tighter with, the neighbor you'd like to be more friendly with, etc. etc. etc.

I've got two weeks under my belt and feeling absolutely great about it. It is Super Bowl Sunday morning here, which was a "drinking holiday" for many of us (not that I needed an excuse). Zero desire to drink, and feel I should have no problems getting through the game even though it will be bombarded with beer and liquor advertisements. Also excited to have a fairly normal Monday morning at work tomorrow, free of the massive hangover I'd typically sport.

But for all that, I don't know how top navigate a conversation from last night. Had a basketball tournament with my 8th grader. After the game was chatting with a dad I've gotten friendly with at these games. He tossed out the old "You should come over sometime for a few drinks, or we could come over to your place." I agreed of course, leaving it to puzzle through how I'd handle it in sobriety. What do non-drinkers say in these situations?

"I don't drink" - seems a little blind to the real message of 'I'd like to get to know you better/socialize more' and could come off as a rejection or seems no fun.

I could agree and set something up, but am I doing it under false pretenses? I'd have hated going to someone else's house to "have a few" and find out I was the only one having any. Now, most "non-drinkers" might crack one and be done, while I slugged through a handful or two...

I want to hang with this guy, he's cool, his son is a good kid, we have a lot of shared background/hobbies/etc. As an added hurdle - my wife has gone dairy-free after testing some allergies and does intermittent fasting. I am trying to go Keto/Zero Carb - so "we'll order pizza" doesn't really work super well (though we could take a night off of that).

Any other ideas? What has worked for you? I haver already realized just two weeks in how dreadfully boring drunks are (I still attend a weekly zoom with some college buddies - that is usually just a handful of us getting hammered and I'm logging off earlier and earlier). I want to hang with drinkers and non-drinkers alike - as seeing others drink doesn't tempt me... it's the thought that I have to "stand-out" or be noticed as a non-drinker I don't like.

Thanks, just typing this out already is helping me see some things more clearly. I've already got an idea to maybe some some chicken wings and provide "soft drinks for the kids (and my wife and I)" and they can bring whatever they'd like to drink, letting them know I don't drink much, or am "on a break". Any other ideas? What has worked for you? Help this social butterfly grow new wings now that his drunk ones have fallen free.

Love you all, IWNDWYT! :D
