For low BS, get glucose paste or tabs. They’re portable. Keep them with you at all times.
But your sugar shouldn’t be dropping that low if it’s controlled and your diet is appropriate. First off, if you’re drinking anything other than water (e.g. soda), that’s gonna send your sugar through the roof. If you’re a type 2 diabetic, it’s highly likely your diet brought on your diabetes in the first place. And if you don’t change your diet now and get your diabetes under control, the hard truth is that you’re gonna take years off your life. My first recommendation would be for you to ask your doc to refer you to a dietitian. You need to learn how to eat right.
