Wow...that really is unusual Lori! To have bright green poo...and it seems directly related to taking the Bentonite and psyllium?
Why don't you try just taking the psyllium and see if you still get green poo? Then maybe that will tell us something... When your poo was bright green was in in a regular poo shape? (I know! This conversation is tooo much!)...or did it look different? hmmmm.
I have only gotten out (in 4 flushes) maybe...160 stones! Not much eh? We'll see what happens next...
