This happens to some people, especially beer drinkers. ;)
You're probably feeling icky right now because the epson salts have dehydrated you. Drink tons of water and see if you can get a colonic
done. Sometimes it takes 2 days for the stones to make it through the colon; you need to take fiber, eat high-fiber meals, and make sure the toxins that DID get released get OUT of you FAST. :) So keep those bowels moving!
GCG would definitely help, I saw a lot of stuff I'd never seen before after taking it. I also recommend Coptis, in case your liver is unable to produce a lot of bile at once. After taking Coptis for a week, I started having many more BMs than usual after eating oils. Once I ate buttered popcorn (YUM!) as my late-night snack and had 4 BMs the next day! So I think it really worked in helping my liver to produce more bile, as bile stimulates peristaltic action.
Best of luck! :)
