Kath,
I wouldn't use Noivomix, simply because it is not the best choice for T1 diabetes. But, by all accounts, it is a good product and should work well for you.
Novomix 30 is a premixed analogue coktail. Which means that it is a mixture of two different insulins - one short-acting and the other long-acting. The idea is that the short-acting insulin covers the meal before which you inject it it. And the long-acting insulin covers your phisiological insulin requirement between meals. Novomix 30 contains 30% Novorapid. So it starts working after 10-20 minutes. The other 70% is a "longer acting analogue", presumably NPH.
Injecting it before your morning and evening meals should keep your post-meal blood sugars in check. You may find that a carby lunch causes a blood sugar spike, as action of the morning shot will be tailing off. But you should be able to manage this simply by restricting high GI carbs at lunch time.
I would suggest testing 1, 2 and three hours after meals to get a feel of how this insulin is working for you. And you will be able to identify patterns more easily if you get into a regular routine of eating and avoid excessive exercise, at least to start with.
Cheers,
Mark
