You might have seen your doctor by now!! When you were doing fine with Lantus
dose of 96 and now the requirement is close to half of that dose, you need to rule out few possibilities- One that you might have had started new type of exercise in your daily routine, two, you might have cut down your carbs and/ or fats significantly from your diet. Three, a little worrysome, that you might be having starting stage of diabetic kidney
disease whereby you tend to manage well with lesser insulin
. So please check for that. Changing the usual insulin site, rubbing the injection site, taking hot water bath after the injection are other temporary reasons for having good control with lesser dose but if you are managing well with lesser dose for a long time now, be aware to keep records and discuss the matter with your diabetes
nurse educator and your diabetologist
. All the very best.
