Hello Kelly, Novomix insulin is designed for an individual with type 2 diabetes. It contains 30% NovoLog and 70% Protaphane. Because of the high amount of basal insulin (the Protaphane) it is not recommendable for type 1. This whole regime of two shots per day is the stoneage of diabetes treatment. Todays medications and treatments are far far superior.
You need to find a good doctor first. Most preferably an endo specialized on diabetes. Then you should switch to a different treatment called bolus basal. In this treatment you will use two different types of insulins. In other words the fixed 30/70 ratio of NovoMix is replaced by dosages appropriate for your individual needs. Most preferably the outcome will look like this:
a) you will use NovoLog as bolus insulin for carbohydrates and corrections of the blood glucose. This insulin is injected when needed. If the blood glucose is too high you can correct it easily.
For example: if I intend to eat 30g of carbs I will have to divide these 30g by the insulin to carb ratio of the current hour. The carb to insulin ratios can be different from person to person and from hour to hour. It takes some time to find the correct ratio. But with little tweaking they can be found. After 1/2 year of tweaking it will be perfect in my experience.
b) use Levemir as basal insulin to cover the basic needs of the body. If the correct dosage of this insulin has been found you can skip a meal if necessary and still your BG will be stable. This insulin should be injected every 12 hours = twice per day. Important: Do not go on one shot per day!
c) learn to count carbohydrates and the mechanics of diabetes treament with the bolus basal approach. Learn to adjust to sports and other physical activities. Reclaim your freedom by stepping out of the cage of musts this NovoMix is creating for you right now. It might be more complicated first but it will pay out.
Recommended books: "Using Insulin" by John Walsh and "Think Like a Pancreas" by Gary Scheiner. Each of them go into detail about calculating your I:C ratio, how to optimize basal insulin, how to do corrections, etc.
d) get a smart phone and manage your diabetes diary online with our Glucosurfer project. It might be too slow in Australia but it is worth a try. This system will also offer a bolus wizard. This wizard will help to calculate the dosage. You just enter the carbohydrates and the system will take the insulin to carb ratio at the current time to make the calculation for you.
