Is not drinking socially a taboo in business circles?

Well, in some circles such as sales where business negotiations are most often made over a couple drinks, I guess it would be. So, what do people like myself do?  Should we be called social misfits or awkward, or inept and incapable for sales roles?

I thought, in fact it was starting to becoming fashionable to say that you don't drink!  I am wrong.
