I have a question about hypoglycemia. I am diabetic for almost forty years and for a few years I had diabetes burnout and gained a substantial amount of weight. In order to lose that weight, I dieted down to a very low weight with severe carbohydrate restriction. I went from taking insulin and glucotrol to only 500 mg of glucophage. Yesterday I ate something inappropriate and my blood sugar zoomed to 425. I woke up early this morning with a 325 and treated it with 5mg of glucotrol. I quickly went down to 50 and had severe hypoglycemia. I am worried that during the evening this will happen again if I eat low carb. How long does glucotrol work? Will I need to keep my blood sugars higher throughout the day so I don't go low like that? I was very symptomatic and shaking with little ability to think. TIA
