I am still on vacation and have time constraints with this
laptop and wifi....

I am looking at this thread a bit each time I log on, and have some questions...if you can answer them for me, by next week when I return I may be able to offer some opinion...

Right now I wonder what your B12 level really is.

Also did you or do you use:
Nitrous oxide

Go to raves

smoke MJ

were given antibiotics Cipro/Levaquin, or Flagyl (metronidizole) in the recent past.

exposed to formaldehyde in new building/carpeting or
been varnishing or stripping furniture.

drink well water or exposed to arsenic treated wood

have you had a serum bicarbonate run regularly while using that Topamax? Topamax can cause acidosis which gives symptoms of PN.

I will be back in the latter half of next week, and can then devote more time to your thread. See ya then.
