I am using the Cyano , U was meant to mean Units I think, but I really meant ml so 0.05 ml or 0.15 per day sorry about that.

I stopped my other doses yesterday and took some B1 which seemed to help ( despite being 2 months out of date ) and citicoline. ( waiting for restock for other stuff )

Worrying thing was I noticed the tingling spread to my face a bit like some other poster mentioned - and seems to flare up bit whenever I eat anything .

This reminded a lot of 10 yrs ago at his peak when I had gastro problems ontop of pn as well , as I had to avoid lots of food which seemed to trigger pn as well.

Bit depressing as it seemed to help my connective tissue problems a bit as well , but i dont want to take any chances after only 4 days of this.
