Has vitamin b12 caused my extreme fatigue?
I am currently living in the UK, I was diagnosed with GERD 4 months ago. From reading lots of sites about GERD i knew I had to take some vitamins to help with the lack of it being absorbed from my body with taking GERD medication and blood pressure medicine for my supposed high blood pressure which only happened when I had the heartburn attack which diagnosed my GERD.
Due to the medications I was taking I was having problems with sleep and fatigue so I started taking a multivitamin called Multibionta which seemed to be helping as I was sleeping a bit more. After a month though my fatigue started to get worse so I figured that maybe I need a higher dose of the vitamins to help with giving me more energy during the day.
I bought a liquid medicine called Feroglobin which didnt taste good but it immediately gave me energy, I did notice though when I was out the first day I took it that for a brief moment I felt exhausted but then perked up again. I figured it was due to not taking enough of the feroglobin so I took a little bit more during the evening to perk me up which it did, but then I wasnt able to get any sleep so I woke up tired and lethargic (more than usual) and so I took sum more Feroglobin to counteract this which again perked me up until about 3 hours later when I could feel myself getting more and more fatigued to the point where I had to go to sleep which I couldnt. Since then I have had trouble getting sleep, my blood pressure has gone up and I feel so tired during the day that I cant do anything much apart from go to work which
takes the most energy that I have left out of me. I then stupidly thought to try just b12 supplement on its own at a higher RDA than the feroglobin had, I didnt really notice much difference the first time, I did kind of sleep ok the first night I took it, but again next day my fatigue was still there so I took another one which had no affect at all. So now I am burdened with extreme fatigue to the point where my legs are aching all the time, the fact I am unable to sleep throughout the night has caused me to have headaches and weird pins and needles feelings all over and its been so horrible how its affected me in my life to the point of depression.
I asked my doctor if taking b12 higher than the RDA affected my fatigue like this and he said it shouldnt have but I feel otherwise. I will never take a supplement above the RDA ever again, and whether my body can recover from this extreme fatigue and lack of sleep I will never know. This is my experience with B12 anyway, I was wondering if you ever came across this issue with other people? The only reason I stopped the Feroglobin was on the advice of my doctor as I didnt tell him I was taking feroglobin or the b12 supplements.
I wonder how I would be If I had continued to take feroglobin knowing what I know now. I was reading up on what I may have and I think it could be adrenal fatigue, I may have just burned myself out trying to keep myself awake at work due to the fatigue before. I am still keeping myself awake at work but much harder which has make me unable to sleep even more.
