Hello,,
My name is Markus and I also am starting today. Last week I managed 5 days (I did juices mixed with Olive oil and water, salt only once and a special soil, which I took 2-3 times a day)
I didn´t have any problems with energy, I was awake very early in the morning, my thinking was clear and I was able to function physically great. Doing it with water alone gave me a hard time, especially at the beginning.
So you should be able to perform ok, after about the 1st or 2nd day.
I took the salt with lukewarm water.
All the best for you. I will be also here reporting
