Thanks everyone for your insights! I guess I will see how I feel tomorrow. I didn't think I got much out of my first flush, but I slept through the night for several days, without getting up to pee. I also woke up very clear headed. It is worth it if I get that feeling again.
I just purchased the kidney tea mix that Andreas recommends. He also recommends taking a few drops of chanca pirdra several weeks before the flush. I will try these two things before my next flush next month. Any other suggestions? Andreas doesn't recommend a parasite flush before liver cleanses. I'm not sure if I have any parasites. I looked closely but, of course, I'm not sure what I am looking for...
