So, yesterday I finally screw up the fast...
The morning started really well as already described and the day went well, too, then I did what I believe was the main mistake. I thought that Psyllium can improve greatly on the cleansing process so I took it (at around 4PM), as it turns out, it's not a so good idea if some food doesn't follow and since that time I felt really, really weird.
For the rest of the day I experienced suffering and I was contemplating greatly on the whole fasting thing and the idea of balanced diet (combination of food, air, light and sleep). When I came home I was in agony!!!
So, I got home, had a coffee with my wife and during the chat I found out she didn't eat much today which made me thinking of food even more. Then I decided to do something I originally intended to do on Sunday, I took the scale and found out I didn't lose even 1 gram during the 2 days long fast. So at 11PM I finally succumb to the idea of cancelling the fast and went to the kitchen to make some fish&chips (one of my favourite meals).
I will append some pictures taken during cooking as after the food was finished I was too busy stuffing my mouth to take a picture of a finished meal :D. So, the advice for the next time is: "Avoid psyllium during the no food fasting".
