Google backs me up on it. Magnesium is making my stomach miserable. I emailed my GP about it--even though I was taking it with food and topping it off with yoghurt I was ending up with an aching stomach and a feeling of fullness that lasted hours.

He suggested I lower the dose, but I can't do that with these pills, or stop altogether.

I'm thinking I'll stop because I wasn't noticing any positive changes to the migraines anyway.
