Just because one can handle fasting and physical and/or mental (Computer) activity does not mena there is not a cost. Absolutely you will not get the same results as if you follow the program 100%. I personally do not relax 100%, I am satisfied with my results and I do rest quite a bit. This fast I am on now has gotten much easier and I have more energy. Still I am finding it easier to rest because I am really motivated over the healing result I have acheived with 90 days of fasting over the past 26 months
