My husband has been working long hours recently, my toddler and preschooler are in rotten moods and I need to pack for a holiday we're going on tomorrow morning. I drink alcohol pretty infrequently (maybe once a month?) but I've just been to Aldi for a few bits and impulsively bought a couple of canned G&Ts. I really want to have one now, as a 'treat' to perk me up a bit. Would that be unreasonable? I'm not planning to make a habit of it.
