Hi Irish,
I thought I was better than everyone else when I was drinking too - it's only after I stopped I realised how stupid I was.
I'm glad you're reaching out both at AA and here.
I think the communion wine thing is a very personal decision.
I know guys who take it because they genuinely believe in the Catholic doctrine of transubstantiation (the bread and wine actually become Christs body and blood)...but if you're not sure, I'd reckon it's probably best to stick to the Host until you make a decision down the track.
Welcome
D
