Great idea on the raspberries & cream, I’m aware you are on Gliclizide so it depends on how your BG is at around that time, I never snacked if I could avoid it when I was on Gliclizide (and I don’t snack now) but I can understand the temptation when everyone around is eating something.
If you’re looking for low carb snacks, cheese, hard boiled eggs, packs of meat, small handful of nuts, a few berries with either cream or Greek full fat yoghurt. You can get some low carb snack bars but they’re not the cheapest thing and some people find they raise their BG, a couple of squares of 85% chocolate, bacon on its own, if where they get there bacon rolls from maybe do egg & bacon on their own, if you have a microwave - leftovers from dinner the night before
