Speaking as someone that can happily drink a bottle of red wine on an evening, then have a few beers, and still function normally the next day, getting the kids up, getting everyone to school and work on time, working productively for eight hours, picking up the kids, sorting dinner, helping with homework, bedtime routine and then house work, before cracking open another bottle for some quality TV, all the while posting on here. The deleterious effects of booze, certainly on others, is more down to temperament of the drinker than the booze.
