Help What is best water fasting time?

[HopefulSleep]

I will do it tomorrow and the food fasting will be 22 hours in the end.
For the water fasting I wanted to do 8 hours but is there any advantage doing it this long instead of 2-4 hours?
When is it long enough?

Generally water gets absorbed really fast. For gastro procedures they have you stop drinking water 2 hours before.

So you don't think there is an advantage in fasting longer?

I don't think so. You would probably just get dehydrated a bit.
