None of the things you suggested should have had any effect on your liver flush.
The only thing I saw that you did different was Dr. Clark suggests beginning the flush at 6:00 p.m. with the first Epsom Salt mixture and two hours later, take the second. The olive oil mixture is to be taken at 10:00 p.m.
Try another flush and see what happens. Use a glass pitcher and don't chew gum.
