Metformin and Feeling Awful? What It's Actually Doing

If you just started metformin and feel worse instead of better, here's the part no one told me: it's probably working, and that's exactly the problem. Four years ago I left a hospital in a foreign country with a bag of six heart and diabetes medications and no idea what any of them were doing to me. This is the honest, plain-language version of what I've learned about metformin since. What it's actually doing to your blood sugar, the two-taps way to picture it, the nutrient cost almost nobody checks, and why the number coming down is the beginning, not the end. Not medical advice, just what I wish someone had told me.
