I am getting ready to do my second ever liver flush. The first one was what I would characterize as a minor success. I followed the directions the first time to the letter, wanting to increase my chances of getting out stones. The only real problem I had was terrible thirst. Normally I drink about a gallon of water a day. After 2:00 pm, I was OK for about an hour, then I started to get so thirsty I could hardly stand it. Is it OK to drink a little water before the first ES / juice dose? And in between? Please advise...thanks.
