Cathy,
Not sure I'm remembering this correctly, but haven't you been having problems getting your numbers down? You might want to discuss with your doctor adding a medication to reduce your insulin resistance (or increasing the dosage if you're already on one.) Also, if you haven't yet done so, you should probably see an endocrinologist...your numbers are running way to high. I also question the use of novolog 70/30...I suspect you're not getting enough bolus insulin (the 30%), and might be better off learning to count carbs and going on a Lantus/humalog or Lantus/novalog regimen, which would give you more rapid-acting insulin to cover the food you eat.
As for the immediate situation, I agree that you should be calling your doctor or going to the ER.
