Insulin lowers blood sugar, rather than raising it. For T1s, I would imagine an insulin pump would help prevent mistakes where you misjudge how much insulin you need - but I'm not a T1, so can't comment on real-world effectiveness.

In my particular situation, the best way to manage things has been to go keto - any more than around 5g of carbs causes me to have a hypo, presumably because my body over-compensates and releases too much insulin. I switched to keto a few years back, and my life has been so much easier since then - I went from having a hypo multiple times a day, to very rarely. It's been several months since my last one.

If I hypo (or in the more general case when a T1 takes too much insulin by mistake and hypos), the "healthier" option is to use glucose tablets or a glucogel tube (a measured dose of glycogen, often carried by T1s).

But when you're having a hypo, you don't always think clearly - it's fine if you catch it early enough, but otherwise it really is like you're under a magical compulsion to eat as much sugar as you can; I'm not sure there is another experience I can relate it to. And once you eat some carbs, it's 10-15 minutes before you even start to feel better - believe me, you can eat an obscene amount in that time!
