I think the rules can be pretty flexible.   Whatever amount of fasting time works for you.  I would keep drinks during fasting no sugar or very low sugar.

Stick to a schedule. Whatever schedule works for your life and body fine, but stick to it. One of the goals of IF is to regulate your hunger hormone and insulin resistance.
