I took a night flight from a holiday in the sun, and with the 4 hour time difference (from UAE), missed breakfast. On returning home, took my usual supplements of B12 Methylcob. 5000 MCG, with a B Complex. As soon as the nugget dissolved, my face, neck and upper chest started burning red - looked like I had been scalded! Was this because I had inadvertently missed breakfast (it was a night flight), or because I had been in the sun? I also had red blotches come up on my arms - scary! Fortunately, symptoms started to subside after about an hour. Am a bit worried about supplementing again! Advice please?
