I noticed some time ago that taking vit with citrus bioflavinoids was spacing me out. I noticed this because the days I stopped taking it, I felt so much better - more alert, focussed, clear minded. But as soon as I took it, I felt worse, not better. I think this is because of the citrus, which doesn't do me at all.

So, I am going to try magnesium ascorbate powder and see if that helps with other symptoms. But definitely I feel better not taking vitamin c, when it should be the other way around.
