I also have chronic eczema and I did a Water Fast last week for 3 days, I know it's not enough but i felt my digestive system much smoother and my skin got dryer and not erupting ..... and skin also got really soft.
I'm planning on another more than 3 day fast, possible 10 days.. I would like to see how you are going.
you should drink some good salt water and it provides you with some essential minerals for the detox. I use himilayan ... and the fast was much easeir to do.
