For higher carb meals, l take 4u of Afrezza a little bit after staring the meal and then follow up with Humalog an hour after the meal. Based on past experience, if I know I’ll spike after a meal, then I’ll also take a few units of Humalog halfway through the meal and monitor things to see if I need a few more units 1-2 hours afterwards.
I rarely use the 8u Afrezza cartridges so I have been splitting them into 2u’s each. Thanks @mentat for the suggestion and great video showing how to do it!!
