Does a non diabetic's blood sugar flucuate all day too? For example, before lunch I was 76, one hour after I was 102 (is that jump bad?), then two hours later I was 83. Now I am 70 but missed my afternoon snack and feel hypo. I am eating something now but geez, will I always have to eat every 3-4 hours? And what exactly does metformin do? I just started taking my second 500 mg extended release pill in the morning and my appetite is ZERO! Sorry to be a drama queen. I guess I just need some support and my husband is working late.
