My sugar is high

Call your doctor/advice nurse immediately, drink lots of water and ketone test. Do they have you on a different rate of insulin depending on how high you are?

My first suggestion is insulin, but if you can’t because of the whole 2-hour rule, water and exercise. Now, I know that when my sugars get super high my vision goes down the rabbit hole and I feel dizzy, almost “low-like”. So maybe do something that doesn’t involve standing, like sit-ups or push-ups. Heck, you could probably just stretch and it’d help a little.
