Sometimes I forget to take my insulin before I eat. Should I go ahead and take my shot after I eat?

You can take your insulin after your meal, but the dose may need to be adjusted depending on how much time has elapsed betweem your meal and the time you remembered to take the insulin. If little time has passed and you remember to take the insulin right after you have eaten, it is usually safe to take your pre-meal dose. If, however, you remember 1 to 2 hours after your meal, the dose will usually need to be adjusted to a lower amount to protect you from unwanted low blood glucose levels 3 to 4 hours after the meal. How much of an adjustment you make is something that should be discussed with your primary care provider, your endocrinologist or your diabetes educator.

I would think that it would be no different then just giving yourself a correction bolus. You need to know how much one unit of insulin will drop your blood glucose. Then do the math. If you're at 300 two hours after eating, you need to give yourself the correct amount of insulin to get you down to whatever your goal number is. You might also want to do some physical activity to get yourself to come down or perhaps combine a bolus with some physical activity.
