Alcohol pushing is really prevalent. But you can limit your exposure as well as your sensitivity to it.
I don't socialize with people who push alcohol on me. My friends know I almost never drink; I cut people out who keep pushing drink on me.
I rarely eat out -- when I do, I tend to pick little ethnic restaurants who don't have the permits to serve alcohol. I figure they need the support and I they usually serve good food.
I don't own a TV. Alcohol was never a part of holiday celebrations in my family.
I make really deliberate choices to avoide the irritation that pushiness leads to. I really wish I didn't have to, but I think it's sort of like being a minority in a majority culture -- kind of like my Jewish friend when everyone asks "what did you get for Christmas?" or "how do you make your Christmas ham?"
