CNW: Constipation cure?

I recently spent 3 weeks with friends, at two different homes, eating very healthy food (lots of fresh salads, fruits, veg juice, veg/fruit smoothies etc - much as I eat at home, in fact) BUT I was totally constipated for a week and semi-constipated after that...until I started using my CN unit to filter the water: immediately back to normal. Wow!
