Congrats on 16 days blankspace. It is awkward being in situations with other drinkers, especially early on in sobriety. I also tried to "test" myself several times by going to many of the same places I had always hung out and drank non-alcoholic beer or soda. I was quite pleased that I was able to do so but after not too long i grew very weary of it because it just wasn't fun. Pretty much all I did was wish I was able to have a drink with the rest of them or resent the fact that they could drink alcohol but I could not.
I personally feel that "learning to live without alcohol" means finding different things to do and different people do to them with - vs. living my same life from before just without alcohol.
