Hi Lynn
I cannot help you with the insulin but wonder if you need to see your DSN for a dose adjustment if they are that high. You do not say how long they have been that high or when you were changed to the new drugs.
It is a shame that you have to eat that high a level of carbs. Possibly add some fat to the pasta to try and slow its digestion down a little. Do you eat low GI forms of Carbs?
When my numbers were going high I would do some moderate exercise like go for a walk or put a film on and sit on my bike pedalling. If you can do exercise you may fine it helps.
Sorry I can't be much more help.
