If you're treating your own hypo, you have to do so virtually on automatic pilot, so if you've been having milk with sugar for decades, like Sugarbum's Dad, then that will come naturally.
I think there's an element of a need to act fast, perhap preventing blood sugars falling lower, rather than worrying too much about exactly what you eat. I know that others disagree with this, but adults are different to children eg it's vital to test that blood sugar is OK and has been OK for 45 mins before driving; if not driving, then approach can be a bit different, although it's still best to get back into normal limits as soon as possible. Often it's better to have what's close to hand, rather than go down stairs in the dark, for example, which is why sweets beside bed is vital. A kayak becomes much more unstable if you try to pull food out from under your spray deck, but the need is removed by having sweets etc in bouyancy aid pockets.
