In lieu of the condition of your father who has had a stroke
also,there is no point in keeping his sugar levels under tight control.
Ther is no point in keeping his sugar levels around 70 to 100.
The danger is that he can land up in hypoglycemia
any time which can prove to be fatal ,if it goes unnoticed,specially in the night.
You can talk to your doctor and reduce his night dose of gluconor G2 to half.This shall enable him to have more glucose
level in morning and avoid drowsiness
Also make sure that the anti diabetic medication should be given in night only if he is taking his meal.
If he doesn't take meal in night for some or other reason,his night dose of GLUCONOR should be withheld and not given.
I hope it helps.
