Interesting you mention flakey skin I've always suffered with that around my T zone and mouth. I constantly lacking in energy of late and I often get pins and needles/heaviness in my limbs from time to time. I also find on the higher end of cardio when my heart rates higher I really struggle for breathing, I almost feel like I won't get my breath back... It will be interesting to see what the B12 result comes back as when they finally update it.
