I can't believe it, it took me at least 10 minutes to put an answer together (not good typist) and I lost it. So here it is in telegram style.
Good flush! Use Alka Seltzer Gold (no aspirin) during the night (see Kelley's cleanse.
You can throw up, if you want to, flush still works.
Since calcified Gallstones use ES but use less.
Heartburn and nausea normal with Gallstones problems.
Try other flushes, till you find one that you like, they all seem to work. I tried them all, but last 5 (out of 25)have been
the Oxypowder one (www.ghchealth.com under superphos30). It is similar as phosphoricacid (see cleanses) one.
I use softeners like ACV, malic acid, chanca piedra, phosphood etc., not all at the same time I switch of.
I saw your question on Andreas forum and he is very good.
This is more a combination of all I have read.
