Gibby, I have wondered about that, also. Where is the good Doctor to help us out here? What has become of him? Not that I don't appreciate Pioneer and the others who have been so kind & encouraging!

I'll try to give you some "pros" for doing it before bed. You can just go to sleep afterward. You're lying down and not doing anything strenuous. Just resting. If you just lie still after a flush, you might not experience so much nausea. Getting up after a flush always made me a little nauseous.
My body did best with just resting after the flush. I try to lie on my left side when I go to sleep because that's the way the liver empties is from Right to Left. I do get up and play around on the computer afterwards, (for a while), lots of times. That's not strenuous. I always feel very tired the night of doing a liver flush. Next night too. It might happen to you. If you can possibly do it, I think it's better to just let the body rest and go to sleep after a liver flush. It may have something to do with more stones coming out as we're supposed to lie still during the flush, anyway. You're already telling your body you're beginning to be good to it and clean it out, so take it easy on it thru this program, if you can.
