It can seem festive and fun to fill up your glass, but it’s easy to lose track of how much you’re drinking. Alcohol makes some people feel merry, but it also makes some people feel combative, or self-pitying, or lowers their inhibitions in a destructive way. I basically had to give up drinking because alcohol makes me so belligerent. And if other people seem to be trying to avoid or curb their drinking (or their eating, for that matter), don’t make a big deal of it or urge them to indulge.
