I think that freaking over freaking out actually makes you normal, in my world view.

I'm not a huge fan of CBT, but it seems like your reaction may be in part about your distorted beliefs about consuming alcohol-- that "craving" means your an alcoholic, that drinking one drink means you'll turn into your father, etc. It might be a useful exercise for you to explore this-- there's a sticky in case you've forgotten at the top of the forum about the 10 top distortions and their "corrective" statements. It might be that the way you think about alcohol is a variation of those distortions.
