Hi everyone I have a question, I have been taking 15000 mcg of Jarrows B12 under the tongue for 5 months as I have enlarged red blood cells, folate ok, dreadful fatigue originally diagnosed as ME/CFS. Such low blood pressure that when I stand up I have a sharp pain in my head, heart pounds off and I am dizzy and faint. Muscle twitches and jumps when I am trying to sleep, lots of ectopic heartbeats, stomach issues, peripheral neuropathy in my feet and top of head, strange walking gait and very wobbly walking. Cannot walk far.
My doctor will not treat me even though I have enlarged blood cells and do not drink or a vegetarian as my B12 6 months ago was at 660. I also have an underactive thyroid which was getting worse though in range at 3.90 I had been left on 50 mcg for 18 years.
When I first starting taking the B12 10,000 then upped to 15,000 I did start to feel a little better, now I feel back to square one, if there any of you out there that take more than 15,000 mcg's of Jarrows? am I ok to up it even further?
