What’s more interesting is how we all look at snacks to keep us high in a different way. My orange juice is what helps keep me high but I call it a hypo treatment because I would definitely hypo without it. I don’t use cake or biscuits in that way, where as a lot of people do. If I didn’t count my orange juice in my coatings, I would definitely be paying a lot less.
I have various types of low treatments and preemptive-treatments.
If I'm going for a walk, I'll reduce insulin the meal before and have some fruit. I buy in-season, easy to portion fruit like blueberries, strawberries, apricots and oranges. I buy these with my blood sugar in mind and consider them a low treatment as they help keep my blood sugar up on walks. I can easily spend €5 on this type of fruit a week (we buy at the weekly market, so it's not always the cheapest option, but it is tasty).
If I'm slowly heading low with insulin on board, I pre-treat the low with granola or crackers if I catch it really early, and gummy candy if catch it a bit later, but not yet low. I keep these on hand specifically for this situation and would consider them low treatments as, like you, I would have gone low without them. I think of these as things that nudge my blood sugar up to prevent a low. Each bag costs €1.50-2 and lasts about a week, but it's eaten by others in my household, too, they just know not to finish the bag.
I have Dextrose Energy tablets for actual lows. I'm in Germany and they cost €1.79 for 40g of carbs. I usually treat lows with 10g of carbs, so that's €0.45 a low.
I also get small 200ml bottles of juice that are tasty, in glass bottles (no plastic) and 20g carbs per bottle. I have them when I really need something fast and will usually start with half a bottle (10g carb), sometimes needing the full bottle. Sometimes I take them on walks and sip as needed. These cost about €1 each.
My insulin sensitivity varies a lot with my monthly hormone fluctuations and I don't always switch profiles quick enough to stay ahead of the changes.
I don't think my hypos are always bad management, they're just something is going to happen when you need to manually do something that your body should be doing automatically, but without all the info your body would have (like hormone levels).
I'm happy to spend a bit more to treat lows and nudge my blood sugar up when it needs it.
