insulin doses

does anyone else find that when you inject a large amount of q/a insulin it has more of a quicker lowering effect on your BG levels than a smaller dose?

i find that anything over 14 units effects me significantly quicker. i had a full xmas dinner and xmas pud for which i took 16 units and a hour and a half later i was under 4.0. even when i know my CP counting is correct the same thing occurs. itake a 1/1 ratio for all my meals.

If you have a larger meal it takes longer to digest, therefore the 14 units will be working ahead of the time it takes for the carbs to be digested. Chances are even after a low so soon after the meal, you will get a high maybe a couple of hours later as the rest of the food is digested.

I have an insulin pump, so can counterbalance this by taking my insulin over a longer period of time, which maybe even 3-4 hours. Taking injections, it may help tosplit the dose, having say half initially and half after 1.5 hours. It's probably worth speaking with your diabetes team about this.
