I was reading the other acne thread and a lightbulb went off in my head, but I didn't want to hijack the other thread. My skin was finally looking a lot better, eating a strict primal diet and not using any harsh chemicals on it. But last week I started breaking out horribly, in spots I usually never have pimples (forehead, neck, etc, but pretty much everywhere!). I couldn't figure out what it could be, but just realized I started taking 400mg Mg at night about 2 weeks ago. Could this be the cause??
