Hi Adrian,
I'm afraid your doctor is talking utter nonsense! Daily lantus units do not need to match units of novorapid, I really can't believe your doctor said that. Some days I can take as little as 18units of novo and 26 of lantus, other days(special occasions/eating out) I may have 30-32 units of novo and still inject 26 of the lantus.
Lantus is a background insulin, there to keep blood glucose stable throughout a 24 hour period. Novorapid is a fast acting insulin designed to cover food at mealtimes. The best way to know if you are on the correct dose of lantus is to fast. Lets say you have breakfast at 8.00 am, then by 12 your blood glucose was 7, your reading of 7 should not fluctuate much between then and your next meal at say 6-7pm. Should your blood glucose rise, to little lantus, if they fall and you go hypo, you will then need to cut back your units of lantus.
I was on the DAFNE course recently, they cover all this on the course and show you how to match insulin to the food you eat. There is no need to eat and inject the same amount each day, that is 'old school advice' not given out now. The principle of DAFNE is to match insulin to the food you consume. They use ratio's to determine the right amount of insulin to each 10g of carbs, or in DAFNE terms each 1 CP, this being carbohydrate portion. Most find that at each meal you may need a different ratio of insulin per 10g of carbs. I can assure you that carb counting is not 'so thirty years ago', it is still in use and the only way of achieving good diabetes control.
I would suggest that you see your diabetes care team and discuss your control, ask about the DAFNE course and enlist, and tell them what your doctor said so you may clarify the situation. I am sure once you enroll on the course and you go back to carb counting, you will see a big improvement in your hba1c.
Good luck
