I'm on Fred's B12 protocol and very very dependent on taking my supplements every day. Without them I'm bed bound or worse. Now my stomach is giving me trouble (for the first time ever) and I'm kind of panicking about this. Symptoms: - A couple of nights/month the last 6 months: Waking up from pain in anus, running to bathroom and almost fainting, lots of very loose stools. - Now, since a few days constant pain in anus, bubbly stomach and strange taste in mouth. No acid regurgitations, no stomach pain or weird stools. Could it be that I've altered the PH balance in some way? Too basic/alkaline? Possible reasons: - Taking lots of ascorbic acid, magnesium and zinc recently. From what I've just read it seems they all make your body more basic. I'm trying to: - Switch from ascorbic acid to buffered vitamin C. Not sure it will help. Any idea of what's going on and what I can do about it? If I could I would stop the protocol for a few days but that's just not an option. Help very much appreciated.
