Fast for min 3-4 days and you will not want to drink coffe afterwards with no effort.

fasting is for me the most effective way to get back on healthy rails, chemical body reset, and afterwards your body will tell you what is good for you, you will be surprised.

However, fasting on water only for few days is not easy, especially for the beginners.

As always, thre is no lasting results without PoW.

good luck!
