Thank you for your quick response, Mrs D.

It's hard for me to know whether I'm unable to process cyano, or whether things are just adjusting. I wake up after being asleep at night for an hour or two and feel very dizzy and sick, delusional and like I'm going to die. I thought that if the B12 was helping me then I would feel better. I have a gut feeling that I'm not processing cyano very well, even though it made my pins and needles go away.
