Last month I did a 10 day MC, then three days of fasting on diluted apple juice. (I choose apple over orange, because I get better flush results when I drink a lot of apple). I did the actual flush on the third day. I had great results with that flush.
This time I am going to drink some apple juice on Friday and go ahead and do the flush. Then I will break the fast this weekend. I hope this works. I like to fast and have my system empty when flushing, although many people just stop eating eight hour before they take the oil.
Passing the stones does not hurt. For some folks the drinks are unpleasent, but you can get them down. There may be some nausea after drinking the oil, but lying very still and letting the gallbladder squirt out its contents helps keep the nausea from getting too bad. I take two Melatonin tablet with the first sips of oil/juice, and I get drowsy after twenty to thirty minutes and unless nature calls (either for me or the dogs) I can sleep pretty well.
Less less you worry the better you'll be. Remember K.I.S.S. keep it simple sweetie.
