Here are the brands I am using for B12 and Folate. http://uk.iherb.com/Jarrow-Formulas-Methyl-B-12-Lemon-Flavor-1000-mcg-100-Lozenges/129 http://uk.iherb.com/Life-Extension-Optimized-Folate-1000-mcg-100-Veggie-Tabs/63828 (I understand I might have started too high in regards to the folate) In regards to my condition, I have stabilised in the last few months. No worsening has really occurred and I believe I am almost near the end in regards to figuring out what's wrong with me (was exposed to a lot of Mercury in my life time, and possible viral bacterial issues). I tried using Fredd's Protocol a few months back, but didn't go far out of fear of possibly doing it wrong and making my issues worse or something (I hear talk of permanent neurological damage, which sounds extreme). I have been doing Andy Cutler Protocol for a few months but haven't really gotten very far into it (only started using ALA a week or two ago). I decided to try B12 and Folate out again to see if it may help my symptoms somewhat. It MAY have, noticed my reading ability has been a little better since I started, though I noticed some issues with my right hand coordination when typing, that has gotten better today though. It's however not that I am concerned about, what I am concerned about is how I feel when absorbing the B12 under my lip. When I am absorbing the vitamin, this is what I tend to experience: 1. Tingling around various parts of my body, kind of like an itch (not a symptom I normally experience to an extreme degree) 2. Itchy sensation around tongue and thyroid area 3. Sometimes a bit more revved up. 4. Strange headaches (like a burning) This isn't really much, but what does this mean? Potassium deficiency, or something wrong with how I take folate? I took the folate whenever pretty much, I later read that taking it a few minutes before the B12 apparently is a better idea. I am going to taper off the B12 and Folate and try it again after getting some Dibenzocide to see if that prevents the tingling. Could someone who is more knowledgeable and intelligent than me explain what this could imply and should I be worried my brain will be turned to mush? I will start with lower doses of Folate next time, I just don't want to mess myself up while my body still has a chance of healing from all this (it heals fast if given the right conditions).
