Lucee - you are definitely not alone! I had the same problem with my liver flush. It helped to use a little olive oil on the area before/after each session on the "throne". I kept a little snack cup w/lid in the bathroom. It seems to keep what's coming out from further irritating the sore parts...
Hope that helps. I used the lax tea for over half of my 16 day MC, and it was easier than the SWF. But, I felt better with the SWF (Salt-Water-Flush) (more complete elimination).
