OK, so.... like I said earlier, the food timing this cycle vs. last cycle should mean he'll drop more this cycle, since the food was 3 hours before the shot rather than with the shot. Which is fine.
The timing of his next meal, at 10 or 11 should be perfect actually. Because if the insulin kicks in around two hours after the shot, that would be 9ish. And if you were to test him between 9 and 10 and see that the BG is down like you want it to be, and not down more than you want it to be, then the food between 10 and 11 should "buffer" the drop right around nadir time and stop him from going too low. All of that is a "good thing".
And it will be interesting to see if the curves are a lot different, how the food and the insulin work with or against each other due to the different timing of shots and food. This could be educational for all of us!
