MDI bolus - more than 7 units

Thanks, that’s a very helpful way to think about it!

You are welcome. The real thanks belongs to everyone in tudiabetes.org. from whom I have learned SO MUCH !

At times, I still am overwhelmed: What went wrong? Was my carb count off? or was it the timing of the bolus?
More recently, I think that as long as my 3, 4th hour are decent, at least my bolus quantity was in the ball park. I try to go to sleep with a decent number. Since we may be sleeping between 6-8 + hours, having a good steady decent number ought to have a positive effect on our overall health and A1C.

now, when you get your head around rapid, I’m going to mention regular, which has a slower curve and might be good for your LC and pizza

I’ve brought up the subject of Regular with my endo. He said, “Oh no, you don’t want to use that”.

Here are my thoughts: Using Regular means keeping another insulin, in addition to Tresiba, Novolog. I would need to have syringes. When I eat pizza or slow digesting food, I will likely need 2 injections: Novolog to address fast carbs and Regular that will peak later. If I use Novolog only for bolus, I would also need 2 injections to deal with the fast carbs and the slow digesting food. My “supplies” would be reduced, Tresiba & Novolog…etc. I’m leaning towards “simplifying” my diabetes management.
Unless…if someone uses only Regular and do not use rapid insulin. I would be curious as to how that may work.

I think @David_dns uses regular, he low carbs

Yes he does. I think he is very experienced; much more than I am. Sometimes I truly feel “clueless”. Tonight, at 9 pm BG was 93 (dinner was 7 pm) . I said to myself, “Pretty good”. 10:30 pm, BG =143. WHAT? WHY? took 0.5 unit correction.

The reason I use different insulins is because they have different characteristics and strengths. Carbs digest quickly, protein much more slowly. Fast acting insulin, with its faster onset and shorter tail, does the best job of dealing with a high carb meal. Regular, with its slower, longer-lasting action matches up better with low-carb high-protein meals.

Nothing magic about it. Horses for courses.

@David_dns, have you ever prepared a fast/regular mix, say 50/50, and kept that around for this sort of thing?

Not sure it would be worth the effort just to avoid an extra poke, but I’m curious.

Not all insulins may be mixed. I know NPH and Regular can be mixed but I believe that the rapid acting analog insulins may not be mixed with Regular.

Here’s the warning in the Apidra package insert:

Mixing: APIDRA for subcutaneous injection should not be mixed with insulins other than NPH insulin.

I’ve heard the same thing, and even if I hadn’t, I wouldn’t combine two substances from different manufacturers whose chemical properties I don’t know. But the bottom line is that my current regime produces highly satisfactory results. It ain’t broke, and . . . you know the rest.
