Good job, taking that first step towards low-carb enlightenment is key.
It's not rocket science, but the simple truth that carbs are what raise your blood sugar and thus require you to take more insulin which then causes hypos and rollercoaster effect. Avoiding carbs and eating more protein and/or fat is the answer. I see advice to eat plenty of carbs for a type 1 as simply and completely wrong. Our inability to metabolize carbohydrates isn't up for debate, or subjective argument. It simply is. The only surefire way to avoid fighting is not to fight, same as the only way to avoid sugars rising is not to ingest them. This is just basic logic, right? Right.
Check out the sugar readings on the Type 1 Grit Facebook group, amazing stuff:

I'd have these sugars most of the time but I also drink here and there, which rocks the boat a bit. At a certain point I'm going to have to face the truth and just cut that out too, as I've already cut out practically everything else -- in principle, though I do cheat once in a while, I often suffer afterwards and I'm nearly at the point where the guilty pleasures aren't worth it, even occasionally. Not quite there though, I've spent a lot of my life as a hedonist and a good curry is lovely. I wish I could find a rice substitute. (brown rice is practically as bad as white, truth be told). Tonight I made chicken breasts and cauliflower-variant "mashed potato" for supper (just swap potato with cauliflower, then add butter and heavy cream with salt and paprika). So easy. Near-perfect sugars for hours afterwards with little insulin needed.
Learning to cook and preparing meals (and especially lunches) at home is necessary. So laziness isn't really an option. But that's ok, the rewards are worth it. It's also cheaper to eat good food at home, if you're smart about it. One thing to remember is that it's hard to eat low-carb when out for lunch, it's all bread / sandwiches (or worse) so make a bean salad at home and bring a lunch box (to be responsible to the planet). There is a way to make type 1 not SO bad, but it requires some planning and attention. And most of all, just the acceptance of Lord Bernstein as your saviour

hehe.
