Having some time under my belt, it's easy to say I don't drink and no thank you. But at first it was cause for concern. My first encounter was to tell a couple of close co-workes that I quit and won't be drinking at the company christmas party. One actually laughed and didn't believe me. The other waited a bit and respectfully ask why I made that decision. My answer was "for health reasons" and he's never brought it up again. At the party, the first co-worker tried to preasure me several times. I actually had to raise my voice at the table to put a stop to it. In later weeks and months he'd ask me if I were 'drinking yet'.
