When I do Liver Flush I drink water after 2 o clock. You can drink water because the kidneys will absorb it quickly. And I think that you should drink water because it helps the kidneys.When you drink espom salt your kidneys have to do a great job. I stop drinking water after 19:30 - 20:00( 2 hours are enough for 1 cupfull water to be absorbed completely). I think you should drink water but stop eating. If you are hungry then eat honey or drink honey diluted in water. It will restore your energy without loosing bile. And it is important what you eat before 2 o clock. I eat baked potatoes without any oils, also boiled rice or semolina is good. Do not eat too spicy or too salty food. Do not fall in the trap of the good taste. Eat simple meals. I eat semolina the day after the flush.
