I have been type 1 diabetic for 24 years now (female), and I am using lantus(once a day) and humalog(3 times) for the last 5 years.
between bedtime and breakfast I am having a drop in BGs of around 10-13 mmols. and then in the mornings, after breakfast BGs shoot up, so my normal carb-insulin ratio doesnt work well.
I cannot understand why this overnight drop is happening, which is becoming scary. I tested BGs during the night and there seems to be a drop of 2 mmol/hour. I am forced to go to bed with readings around 20, so that I will wake up with 7-8. I tried to decrease my lantus intake from 28u to 21u, but the nighttime drop didnt decrase or disappaer, insated i started to have very high readings during daytime. I also tried to take lantus twice a day, but that didnt make any difference either. I am wondering whether this is some hormone related issue ,or whether I have developed some resistance vs humalog so it doesnt work well (and the lantus is too much). I have given up using any alcohol or doing demanding exercise(jogging) for a while becuase they make the matters worse (though i really enjoy exercising).
any suggestions to why this is happening or how i can take care of this would be greatly helpful. thanks
