Jchet, Have not told Dr.
The tiny tablets of METHYLcobalamin are only 50 micrograms.
Anyway, since seeing a TN specialist last week I am now taking 50 mg liquid nightly cabamazepine for a week. Next week , morning and night.
3 rd week, double, 4th week 200 mg twice daily.
Cant understand why so much. I can now brush upper teeth without pain. Only very slight twitch when chewing on right. Perhaps its to try to get the body used to it, so as to be ataxai free as I suffered when on 200mg daily. I fear liver damage after a few months on cabama. Still taking methylcobalamin, but only 150 mcg morning and 150 at night. Thats to try and rebuild missing myelin from the trigeminal nerve. Excess B12 gets readily removed in urine.
The specialist said he would refer me for an MRI. No sign of that yet.
Good luck with yours. James 82 NZ

10 a day seems excessive. Was your B-12 really low? Thanks
