I have finally written down our experience with Apidra in the pump. Caleb has been using it for over two years. We now change his sites every two days to avoid highs. It took me a while to write this down because I doubted many times that Apidra was actually the cause of the clogs. It may not in fact be the issue, but after seeing highs when we extend the use of his Pod beyond 48 hours more times than not, that's the conclusion I've finally landed on.
I talk about it in more detail here.
Everyone's different, but this is Caleb's experience.
