The risk is the alcoholic mind, which will take the sip as evidence that the world did not end and therefore, next time, maybe two sips wouldn't hurt. It is the obsession of the mind that this time will be ok. That is the basic insanity of alcoholism and the fatal first drink.
Yep.
for me, I'd be able to extrapolate that sip into 'sips are ok'...then 'mouthfuls are ok'...then 'half glasses are ok'...then that Golden Oldie - 'one beer won't hurt'.
