Good evening @daan. Good to hear from you!

"I have a very sensitive intestine even before my recent ailments, so that might help get everything healthy again."

I am not an expert, by any means, but what I learned through my experience would indicate you will most definitely benefit as well.

"... you really need to turn it into a habit of drinking at least 1.5 - 2 liters per day.'

Yep! For several years now (once I got the habit detailed above established) I drink abt. 80 ounces (2.36 liters) per day. When first out of bed, I begin my day with 16 ounces (0.47 liters) straight away, washing down two Primal Defense capsules, etc. Won't give it up, now that I understand the benefits ...

If it is not inappropriate to ask, are you on the mend?
