Purity is more than 75 per cent of your health and energy. Nutrition is less than 25 per cent. More fruits and vegetables would help, but that is not the only factor involved in health and energy. You are going to cleanse and detoxify the old waste sites of the body and when this happens you are not going to feel too good. Do not worry about it, it is merely a necessity to get well.
All endeavors require time, energy, pain and suffering.
You take two or three steps forward and one step back. This is progress. As the toxins leave their storage sites they enter the blood stream and they can make you feel worse before you feel better. This is par for the course. The stored poisons will travel through the blood and then temporarily re-deposit somewhere else where there is weakness.
