Hi Kevin,
Like Nigel asked..why the novorapid before bed? That is for food, or very occasional as a correction bolus if you are high. I would think that you are coming out of the "honeymoon" period, and need to get your insulin regime completely overhauled...which is probably best done with the help of your Dr. If you are routinely injecting novorapid before bed...your long term insulin is not working for you..it could be the amount or the type that needs to be changed.
I could guess at something that might help...but a guessis no good...so try and see if the professionals can help?
