hey no probs, LA
actually all my success with isolated b12 supplementation was in the years prior to dx. after dx i realized i was dealing with something much more detailed and complicated than a single nutrient.
i used to get increasing numbness, then loss of functionality, take b12, and feel fine again. stop taking b12, numbness and impairment return, take b12 for a couple days again, etc etc etc.
prior to dx i felt the numbness coming on. i started taking b12 regularly to get rid of the numbness for good - wanted to be in tiptop shape for my academic exchange to australia.
the b12 wasn't working this time.
after my travel shots and a nasty wipeout on a snowboard in jan 06, i ended up in the hospital, and by the night of my 'bon voyage' party at the start of feb, i was hostessing from flat on my back with a wicked post-LP headache (pretty wierd party pics) and letting my guests know that it was a 'NON-voyage' party.. sigh..
i was significantly impaired for weeks, until i'd done enough reading to start to get a grasp of how many deficiencies i was probably dealing with, in addition to b12.
i saw the greatest improvement when i started megadosing b-complex vitamins and a number of other nutrients per a modified 'klenner protocol'. at my worst i walked funny, had that feeling like my legs were full of concrete, i was numb from the shoulders down, i couldn't grip anything, i couldn't target objects i was reaching for (lost position sense, probably related to vitamin e status), spastic muscles, spastic wrists (later identified as probable hypocalcemia) i couldn't breathe properly, i had the ms hug, i couldn't play guitar, couldn't type, couldn't wash my own hair, made ridiculous scribbles when i made credit card purchases, etc etc etc.
3 days into the more comprehensive nutritional megadosing that i did with the klenner protocol, i felt my hands come back a bit, and ran to the computer to see if i could type - and i could. play guitar? yes i could. i'm still not as good as i used to be with full sensory, but i'm working more on playing without looking, in spite of the leftover numbness.
i continued to learn about supplements and made drastic changes to my diet. i got better and better but plateaued with that leftover numbness in my hands, and i have caused certain problems over the years by having been a guinea pig in terms of biochemistry, and megadosing things without fully understanding the consequences first.
have learned a lot and continue to do so. still not on any meds to date.
