I was testing myself and was off of b12 sublingual for 10 days. I only took multivit which has low b12. at first I felt ok. Except just sleeping less. Then suddenly after some physical stress on 10th day I felt awful, lost appotite and my body temp dropped to 35.5 from 36.4.
I skipped the multi and started b12 250 mcg feeling slight improvement. Next day 500 mcg and body temp rose to 36. Yesterday I took 750 mcg and body temp 36.1.
Last night I barely slept waking up many times to pee which has not happened when I was regularly taking b12.
Today I took my multi first and then b12. Body temp 36.3-36.6 but I started to feel nauseous and sweating after lunch. I remembered this happened before when I try to take them same day.
all I can think is that it would have something to do with folic acid.
Any ideas?
Clearly I cannot function without b12 that is for sure. Last time I felt this terrible was before I had taken b12 large dosages.
I feel super weak and hard to stand still my legs are really tired.
