The thing about Lantus is that it doesn’t actually keep working for 24 hours, so you can’t just inject every day at 7AM sharp. In my one-week of experience, Lantus works for about 20 hours and then dumps a person. So to have 24-hour coverage, I’ll have to keep scooting the injection back by 4 hours.
Day 1 7AM
Day 2 3AM
Day 3 11PM
Day 4 7PM
Day 5 3PM
Day 6 11AM
Day 7 back to 7AM.
That’s hard to remember. Hard to set an alarm. So people like Laddie split the dose. Half in the morning, half at night, say. Hmm. This is getting more complicated.
So if you split the dose, you’re never left high and dry, but you’re sometimes having a double dose. Right? So you try to make the double dose parts happen when you naturally need more insulin, like at wake up time?
A drawback for me re the split dose, a major one, is that I am pretty sure I would not reliably remember and/or have the gear on me to do the non-morning injection at the right time.
But how about this:
Stick with one injection a day and program the pump to anticipate Lantus’s sudden departure. That seems easier. But makes it extremely more important to really do the Lantus at the same time every day. (So its departure lines up with the pump’s basal oomph.)
