I've been tested positive for mycoplasma pneumonia. My b12 came up as 750 but I have symptoms that are very like b12d - high thirst, tingling in hands at night, headaches, blurred vision, bad sleep and fatigue. I was supplementing with sublingual b12 (1mg) and my GP asked me to stop taking it, because it looked like the problem was only mycoplasma. I stopped, but a lot of the symptoms came back or were worse. I started them again and it helps, but I'm not sure how much to take because I don't know which symptoms belong to the b12d and which to the mycoplasma. I took 2mg yesterday and it caused frequent urination which I read it a sign of taking too much. Does anyone know how I can work out the correct dose?
Thank you for your help.
