Back on the topic of "is it a thing, or is it a side effect?"

I lapsed off of my Mg and B2 in hospital mainly because they couldn't find me Mg, and took a while to find me B2. Took me a few days to get back into the rhythm of things, and in a few days I was back having orthostatic hypotension--though nowhere as badly as a week or two before the hospitalisation.

Wondering about those things is such a drag. I've had a hard time finding B2 especially in the dosages he recommended--I'm way past the RDA (1.2mg) at 400mg daily. From what I can tell I'll just pee out the excess, but I'm reading now that I should be ingesting as much B6 as B2, and that's patently not happening.

My Mg intake is not too far off the normal supplement amounts, so who knows. Probably just coincidence. So many drugs and supplements are using my body as a battleground that I can't tell collateral damage from a random coincidence.
