Trust me. Even your family is not monitoring your drinking--and even if they are, people do not make a fuss over someone NOT drinking. Have you ever in your life seen a "scene" over someone turning down a drink? All the time--people turn down drinks because they are getting a cold or because they are driving or because they are just not in the mood for drinking. Only alcoholics think that is is ever required and that everyone notices.
It does not have to be a drama.
