I was wondering if anybody had any specific advice, information or reassurances regarding getting headaches whilst on Methylcobalamin.
I'm on 2 x 5000mcg/day (15 days so far) and suffering monster headaches.
I've ordered some potassium supplements and dried apricots as some have suggested potassium deficiency might be causing the headaches.
I don't know if I should change the dose, or even the form of B12 I'm taking.
Some have suggested they might be 'transient/start up symptoms' - has anybody any stories on how long these are likely to last?
