My doctor & I had reasons to suspect some sort of blood sugar issues for me months ago but I lost my health insurance before I could havethe lab work done. Recently I have felt increasingly worse ao I purchased an at home meter just to see if I was crazy or not. This morning I woke up sick as hell like always, my reading was 91. I ate breakfast, which always makes me feel better, and my blood shot up to 164 then a little bit later was at 188. From everything I read that's high. I waited until three hours after eating and tried again an t was down to 74. I'm confused as to what this means. I feel awful today too, I don't know if it's the stress of worrying that I have diabetes or the blood sugar problems making me feel bad but I'm tired and weak and have an upset stomach.
