Thank you ladies, clear answers at last. I never knew you could adjust down as well as up. I am on Insuman Basal, 36 units a day
but because of other health conditions and drugs taken for them, plus age, my fasting levels are higher than most people, rarely below 10, often 14. Daytime ones are high, always have been, because I eat a slice of toast at breakfast, as one of my morning drugs has to be taken with food and I cant stomach the idea of eating anything else. Plus I have to have a little starchy carb with meals. So now this last few days they have dropped right down to 5, which must have been too low for me as I almost collapsed, and now it is low at bedtime, often the same level as my original fasting level and lower, and being scared they might drop too low and I might not wake up, I am eating carbs before bed but still getting 5.5! Don't understand it. So I had been thinking of dropping down to 34 units, what do you think?
