hi there hampsoan
Glicazide does indeed have the power to reduce your blood sugar and bring on a hypo.
I would get in touch with your GP or Diabetic nurse regarding dose.
Did they not explain to you that you could go hypo ?
also it does sound as though you are testing -- so carry on doing that !!
in the meantime -- hope you have treated the hypo with a small amount of carbohydrate and are back with us above 4.0 ??
