No, for X hours. X between 12 and 24, and the first 8 hours of it asleep. Zero solid food, but a little bit of milk in my coffe is a must, I cannot drink it otherwise.

Hardness goes away after about 12 hours. But the 8 to 12 hours are bad enough to call it hard and not do it that often. Hardness depends on many factors, mood, if alcohol was drunk the day before or not etc. I cannot tell the effectiveness of it yet, as I started it when I started to do other changes as well. I am losing weight, but not sure due to this.
