Yes, this is what I am thinking as well. This could be why they tire me out so much.
I also believe that the coffee enemas, although a lifesaver sometimes too, could reduce or deplete b12. As we know, they stimulate production of Glutothione immensely, and Glutothione is believed (or known) to use up quite a bit of b12. If someone is already depleted or nearly depleted of b12, it could be a bad idea to continue the coffee enemas without getting tritrated up on the active b12's, etc. first or simultaneously.
I haven't thought all of this through completely, but am feeling so much better after getting started on Freddd's protocol for titrating the b12's. It's such a treasure hunt sometimes with all of these healing practices. One thing works, but then depletes another. But we keep pressing on:)
