I just started Freddd's B12 protocol and I'm taking 1mg mB12 and 1mg aB12 sublingually, along with a lot of other vitamins that I've been taking for months. I notice that I want to lie down and nap about two hours after I take the B12s. This is not like me. Usually I don't feel sleepy until late at night. Has anyone else ever had this happen when staring the B12? Is it low potassium? Or maybe paradoxical folate deficiency? I haven't added methylfolate yet as I wanted to start slowly. My regular Life Extension vitamin that I'm taking says "folate from lemon" so I doubt if there's much folic acid in it. Is anyone taking either of the B12s in the evening to help them fall asleep? Thanks for your help. I'm reading all the B12 protocol threads as much as I can.
