Maybe I would drink but I don't think I would be any happier or more satisfied than I am now. Particularly if we are talking about very low quantities of alcohol, like two beers twice a month. Right now, I have no desire to drink 1 or 2 beers. Would I if I did not drink so much? maybe.
However, I have to think those who drink very low quantities of alcohol would have no trouble quitting if needed. If a doctor told someone who drinks no more than 2 times a month, and no more than two beers at a time, that they had a medical condition that required them to drink zero alcohol would they really care? Would they feel they are missing out? I doubt it, they would probably go about there life exactly as is and be grateful their medical condition was so easy to fix.
