The SWF (Salt-Water-Flush) didn't work for me -- it just sat there and didn't come out. I freaked because I had 2 pounds of water/salt sitting in my stomach all day. I felt (like you) absolutely horrible.
I followed it up a few hours later with some smooth move tea, then again at night. I finally went to the bathroom at 6:00 that night (boy that was the longest day of my life).
If the SWF (Salt-Water-Flush) doesn't work for you, and is making you miserable, that defeats the benefits of the cleanse. I am most comfortable on the tea morning and night. I know it works for me and my body.
My advice - listen to your body. Doesn't force something in that it doesn't want.
