Hi Lisa...you can do a Liver Flush even if your bowels aren't movin' right along. You can even do Hulda Clark 's Liver Flush without any Epsom Salts (I have a feeling they might not sit well with you? But I could be wrong! But maybe you should take 1 tsp in each drink of water or apple juice instead of 1 tbsp? That's what I do).
If you haven't experienced allergy symptoms from olive oil or grapefruits, then maybe you should just give the Liver Flush a shot...because it really sounds like your liver needs it. Maybe the sooner the better.
I'm doing a flush tonight. (after 2 1/2 day apple fast)
Since you are sensitive, I think that once your bowels are moving, you should try the straight and plain psyllium in water 3 to 5 times a day...then add the Bentonite and see how you feel. (the Bentonite draws out the toxins) Some people do experience constipation with the b&p shakes...but maybe if you take one glass of fresh pulpy juice with psyllium in it, per day, that will help your bm's move along. (the rest of the drinks should be with straight water, or very diluted juice if you don't like the taste - I think it tastes like absolutely nothing! just fine) Also...LOTS of water must be taken.
I would wait until you're well on your way to ridding yourself of toxins before trying a parasite cleanse.
I do hope you are able to start on something...the liver flush seems to be up there on the priority list!
