I've been on it for two days, only 250mg, for insulin resistance following a pretty much lifelong history of (reactive) hypoglycaemia attacks that have progressively crept up from initial symptoms starting around 4.5 to recently 5.5, which is just getting ridiculous. I've stopped having hypo symptoms quite so high and now getting symptoms starting at around 4.7, which is comparatively great and means I don't need to eat as much as often. However, I have been having postprandial levels around 2hr 8.3, which is unheard of for me. I almost never get above 7 even before 2 hours. My doctor said the metformin would reduce the reactive hypoglycaemia and make my levels stable, but 8.3 just doesn't seem right and makes me feel horrible. Any idea why the rise might happen? Obviously, it could be coincidence but that's a pretty weird coincidence.
