Hi Daniel,
You might want to give some careful thought to your diet before you take the plunge. A high carb meal like porridge and toast will be hard to reconcile with non-diabetic blood sugars, even when you use insulin.
I'm type 1 and have been on both regimes in my time.
In my view, there is no comparison. The basal-bolus regime is far more flexible, and much better at replicating the effect of a proper pancreas!
I can understand your reservations though. The prospect of 2 or 4 injections per day ought to make the Novomix option a clear winner. In reality however, the injections themselves are painless once you get the knack. You shouldn't allow that to influence your choice.
Twice-daily regimes are a bit old hat these days, something of a relic from the days before the rapid acting insulins came on the market. You will find yourself eating meals because your insulin demands you do, or risking hypoglycemia if you run late. With basal-bolus you will be able to fine-tune things to suit your lifestyle. You can skip meals if necessary, and correct your blood sugar easily if things go wrong.
Lots of things to consider, but basal-bolus is a clear winner in my book.
All the best,
fergus
