Hi,
Very sorry to hear about your diagnosis. I was on novomix 30 a few years ago. It contains a mix of long acting and short acting insulin. When I was on it I'd have to eat very regularly. Two hours after eating I'd need to have a sandwich or another carby snack. Then two hours after that I'd need to eat again.
Now I'm on Novorapid and Lantus and it gives you the flexibility to eat when you want. Of course we all need the odd snack to maintain our levels, but its much more flexible than novomix 30 and sounds more suited to you.
Also, with Novorapid you can match the dose to the amount of carbs that you eat, so it gives you much more flexibility in what you can eat too. To be honest, I'm surprised anyone is put on novomix anymore.
