Cohiba, I don't really like soft drinks either, hence the club soda (which is called just sparking water I guess in the UK)
Glad that u were able to find the NA beer and like the way it tastes. For me, the plan is to stick with club soda since its zero calories and unless someone hears u ordering it, they'll think ur drinking a vodka/soda, vodka/tonic, gin/soda, gin/tonic, etc.
As you said with the NA beer making u not feeling like an outsider, that's what I'm trying to do with club soda. I'm still steering clear of bars for the time being, but I know that I can't avoid them forever and not feel like a hermit. And given my job involves sales, events happen at bars.
Enjoy your sober Friday night!
