About feeling hungry. I kinda expected it when I started this routine. The fast is short so feelings of hunger do not subside, usually that happens after a few days. So you just have to suck it up. On the other hand it does get easier the longer you do it. I am still somewhat hungry but I don't really pay attention to it. I am cold though, I really need to take a hot bath on Monday evenings.
Also I think taking a brisk walk does wonders when feeling hungry!
I am I and you are you, please allow me my point of view. Because I enjoy your thinking too!
