| It depends on how long your insulin takes to start working. Novorapid starts in about 10 minutes. other take around 30 minutes to get to work.
It would probably prove helpful to you, to find an action profile for the insulin you are using, this way you can SEE when the insulin starts working and that might help you visualise what you need to do to control your blood sugar... yes, everyone is different, but it does give you a better idea of what the insulin is doing. I know it helped me out loads when my DE showed me insulin profiles for Mixtard and Basal and Bolus... made perfect sense!
