Hi,
@paigerobbo_x . I'm a snacker too, and to be honest, there's no reason why you can't carry on snacking if that's what you want to do.
Stuff with no or low carbs in them are no problem at all, ham, cheese, nuts, olives (seriously, give olives a try: you can wind your classmates up and tell them you are just so much more sophisticated than they are!).
Stuff with carbs in them take a bit more thinking about.
You'll learn soon that when you take insulin for a meal, the insulin actually lasts for about five hours.
If you accidentally take a bit too much insulin, your blood sugar might drop too low later on and you'll probably end up snacking on a few biscuits anyway to sort that out. A friend of mine who was trying to lose some weight always used to say, oh, it's so unfair, every time you feel ill, you get to eat sweets!
If, though, you've taken the right amount of insulin, and fancy a biscuit an hour or two later, a small biscuit isn't really going to make that much difference, because it'll be kinda still covered by the insulin from the last meal.
If you want a bigger snack like a bag of crisps, there's quite a lot of carbs in those, so you should think about it as if it's another meal. As an adult, I would take some insulin for that, but you should talk to your diabetes nurse about how much carbs you can get away with between meals without having more insulin.
