I tried a 1 mg tablet of the enzymatic therapy brand mb12 today for the first time. It was an experiment really as im seeing improvements on the hydroxyb12 drops. I did get the feeling that my tmj trigger points were responding more positively to the mb12 compared to hb12. However I felt bleak after about half an hour then angry. The anger is still with me an hour later. Very odd. I'm glad no one is here at the moment as I feel distinctly anti social. It's not making me want to take any more of the mb12 to be honest. I reacted recently with bleakness to SAM-e to the point I wouldn't take it again. TMG however has made me feel better in terms of energy and pain. I wish I understood better what was going on in my body! I do have the partial block as confirmed by the European nutrients lab test, btw. Any insights gratefully received! Thanks.
