I’m similarly attempting a dry January. I don’t drink a whole lot - I’ve been averaging a bottle of wine per week or ~6 beers per week depending on my taste.

Navarro vineyard makes fancy non-alcoholic wine, I’m actually tempted to grab some, there are also a few types of non-alcoholic ciders that are good.

Otherwise, it’s filtered tap water for me or sparkling water if I’m feeling something different.
