Are you better now?
The other thing I do to bring down a big high (after giving a correction bolus of rapid-acting insulin at 1 unit:for every 30 mg/dl over 120 in the mornings and 1 unit:for every 50 mg/dl over 120 at other times of day or night) is wait until the blood sugar has come down enough that I don’t feel yucky and then take a brisk 15-minute walk.
