Rapid-acting Insulin - Overstacking

Wondering what others would do if you had eaten a meal but wanted to eat your next meal before the insulin duration (3 - 5 hrs) is over?

I would inject qa for what I am eating but wouldnt do a correction

Same as Vickyp

Although this was discussed in another thread and someone pointed out that there are meters which will calculate how much of the insulin will still be active in your system from your earlier shot. They take some calibration and setting up though apparently.
