Keep checking 🙂 The role of the lantus is not related to any food you eat, but to deal with the constant trickle of glucose being released by your liver. It does this in order to provide energy to keep things like your heart, lungs, digestive system (and brain!) etc.working when you are not eating. As your insulin sensitivity is increasing, as shown by your pancreas now being able to cope with food without novorapid, it's logical that you will also need less support from lantus. I'd give your nurse a call and let her know your latest figures 🙂
