Hi.
I don't know about insulin causing a stroke...I don't see *why* it would, since it is a product our bodies are supposed to make naturally, but I don't have any science to back that up.
As or the night-time lows, you're right - insulin can cause lows, but as you've found, so can the meds. I think the insulin would actually be more benificial in this case because you can adjust the amount of insulin you bolus to the amount of carbs you've eaten, where you can't really do that with oral meds. Also, as you've said, the problems with your grandmother going too low was "many years ago." I don't know how long ago & what kind of testing was available then, but that may have been improved between then & now.
