Doom/Anxiety Feeling
1 month ago my b12 was 391 and homocysteine 18.4. I began a oral supplement called Homocysteine Nutrients but the methyl b’s proved too stimulating for me. Ive been taking now 3-4 5mg cyanocobalamin tablets each day for 3 weeks now. I responded very well at first but the mood/cognitive improvements have faded. Initially, after eating or exercise I felt short of breath which I read could be a potassium deficiency due to b12 intake. So, ive been trying to get in 2g of potassium a day. This feeling has faded. Exercise does leave me worse off than before, I feel incredibly brain fogged, numb, and anxious after, usually getting a hypnic jerk or two that night before falling asleep.
1 week ago I received a methylcobalamin injection from my PCP and well Im not sure that did me good mentally. For the past week ive been feeling “out of it”, like nothing I am perceiving is how it should be or felt before, or I am getting memories of past times where I have felt this feeling (false perception if memories?), and general anhedonia for activities I usually enjoy (work, video games, music). I will be honest I felt this before the methyl injection but now it is worse and still feels worse 1 week later. Other symptoms like tinnitus, tingling, lighting feelings are back a little bit too.
Has anyone else experienced this?
Edit: also, Ive been experiencing some hair shedding
