Using Libre has helped show me that when I inject my NovoRapid it really takes a good 30 mins or so before it has any effect whatsoever and, even when I am not eating and I am using NovoRapid as a correction, it doesn't actually tend to start dropping my BG until an hour after it's been injected. Has anyone else noticed this? It's made me even more interested in Afrezza as it would be really good to have a bolus insulin that actually started working much faster.
