Is it possible that during the night that the bile from the liver can back up into the stomache? Could this be producing my nausea in the mornings? Any way to stop this? I won't be able to do another flush for at least 6 weeks. I am starting the H. Clarks kidney flush since I had some trouble with them this go round. Also I was told NOT to fast and (veggie/fruit juice) then do a flush. I think that it liked to near killed me this time. Anyone have a similar reaction? Thanks guys, you've been a heap of help.
