Hi American Girl
Welcome
It was never my deal, but I know many people here who've successfully negotiated the drinking while cooking dinner thing.
It might take a while to feel truly comfortable but it seems anything - seltzer, soda, juice, tea - works as a substitute if you want it to
As for ingredients wise I know CarolD has a post about non alcoholic alternatives in recipes - I'll leave that for her
hope to see you around
