Yes, I absolutely know why! It wasn’t random, there is a reason behind everything.
Originally we were trying 2x shots at 12 hours, seeing if you could squeak 12 hours out of it. Remember that was a thing we were not sure about? The duration? If you get 12 hours out of Levi, it’s good because it works into a 24 hour day very nicely, but there is not much wiggle room if it runs out right at 12 hours.
You obviously were not getting 12 hours out of it, so the next thing was to do 3x. I was hoping you could get 10 hours, and do them at 7am and 5pm (and the last at bedtime), because it’s much easier to remember a basal injection when it coincides with a meal. If you take your meal bolus and basal at the same time, it’s easy to remember. You don’t forget your meal bolus, you are used to it. So if you associate the meal bolus and the basal injection at the same time, it reduces the risk of forgetting it. With me on that?
So now, if you do them at 7am, 3pm, and 11pm, it’s a nice and evenly spaced at 8 hours. But, now you have to remember a 3pm basal shot that coincides with nothing! No regular meal at 3pm, so there is a risk of forgetting and missing it. So that is the downside of the timing.
On MDI I always tried to have my basal injection schedule coincide with meals. I would open the fridge, and take out both my rapid insulin vial and my basal vial. It was easy to remember, it became automatic. I wouldn’t ever forget basal because the mealtime shots were the same time!
I wanted to keep it very simple for you since you are not used to MDI, so I thought if you could get 10 hours out of it, the 5pm shot would be easier for you to remember if it was at a mealtime.
All make sense? I promise you, there are no random decisions in anything I tell you.
