I am in a lot of distress. i have been on fredd's protocol for 6 months now and really struggeld all the way with increased headpain and new symtpoms of nausea. My body itch is worse but my energy has generally been better. I continue to get almost daily migraines. I am currently taking 1500 mb12 and 600 of m olate plus most of the co factors ( not TMG or vitamin D). Vitamin D makes me itch even worse. I have tried increasing potassium but it does not seem to make any difference. In desperation to feel better I decided to trial what an increase in mb12 would do- I FEEL A LOT WORSE. I increased my dose of m b12 14 days ago- at first I noticed some increase in nausea and headpain. But the in the last 4 days, i feel so bad i am needing to go back to bed. Since increasing the mb12 the itch has got worse, the headpain is severe, I feel more nauseus and i have an odd sensation of ear ache. My head pin feels like a build up of pressure. My body is aching in odd spots- wrists and right side of back in particular. i have also noticed these past 4 days or so that i feel really tired like i need to sleep more- a tiredness feeling like being hit by a bus- not nice tiredness. Is it possible that the increased dose of Mb12 is just too much for my body- should I go back to a dose of say, 1000 mb12 a day and see if I improve? I have stopped the protocol since yesterday lunch time but still feel pretty awful. I am living on huge doses of charcoal 4 times a day- it does seem to help but is only shortlive as a benefit. I am just not sure what to do. i know I have raised this before, but I do think I have concurrent mercury issues ( ongoing problems with candida and all mercury cheators make me feel as sick as a dog). Any ideas about how I might make progress? I need to do something as i just cannot function at the moment. is it likely that the benefits from this protocol might just take longer ? Not sure if I should just drop back my dose of m b12 or trial some mercury chelation- can someone tell me if this protocol should deal with the mercury issues without needing to chelate? I kinda feel lost, but dont want to stop the protocol althogether as i am not as sick as I was- at leat my energy leels were allowing me to exercise before i increased the m b12 dose.
