The people that stay sober long term change their lives and behaviour to suit sobriety. I had a similar outing when i was drinking and tried to continue it in sobriety, i would go out and drink coffee or diet coke and it sucked ass as i learned the alcohol was definitely part of the experience. Obviously sober things i did whilst drinking i could continue to do if i wanted to but going down the pub with 10 pint mates on a Friday night whilst drinking diet coke was not much fun lol. Lots of stuff to do without drinking though.
