you should be fine with just sticking to the oxy, but the swf cleans you from mouth to anus. very good idea to still use the salt.
cleansing takes a lot of work, and going to the bathroom all day is annoying but necessary at times. you gotta get that junk out.
i did both and used the bathroom from about 6:30 to 11:00 off and on. you gotta go and get all those squirts out. sorry. after that you should slow down to a couple in the afternoon. in other words, once all the salt is out you shold be okay.
i'm kind of a purist when it comes to the MC. I believe in doing it the right way, without all the other stuff. But its a good idea to use oxy to get things moving.
If you really want to see chunks come out, try psyllium and betonite shakes. holy smokes was i suprised to see solids on day 8.
keep it simple. simple is always the best route. simple things are the cheapest.
