T2's can hypo, but it doesn't happen often. I know it happens to me when it's an especially hot day. But it's rare. And then there's a thing called reactive hypoglycemia, and there's a thing called false hypo, and if you know exactly what your bloodsugars are doing (so always bring your meter!!!!) you know what's happening, and might figure out why it happened, and what to do about it. That's the thing.... You could be dipping low for a variety of reasons... You could be high a lot, so when you dip into the normal range you get very real hypo symptoms (The false thing is a bit of a misnomer. Far as your body's response is concerned, you're having a hypo, even if the numbers don't agree. It'll freak out.), you could have reactive hypoglycemia, but it doesn't sound like it (that would come a few hours after a carb-heavy meal, and you mentioned fasting bs), and lord knows what else.... That's why it's really worth it to bring your meter and check the moment you feel off, and keep an eye on things as the day wears on and you either add in sugar or don't. Knowledge is power, and doctors love numbers: if you can show them a few, they're more apt to listen and investigate.
