The reason I do it is that I've suffered bouts of gall bladder colic and the cure is overnight. Now I don't wait til the pain starts and I flush whenever I feel a certain "fullness" under my right ribcage either once or twice a year. I'm sure 3 months is a suitably long period between flushes. I think the way to tell is that if you keep getting stones, then keep flushing.
I LIKE the olive oil-grapefruit lemon mixture (better than the lemon juice-oil)...I even switched to canola the last time and it was tasty, but isn't that EPSOM SALTS drink the most NAUSEATING stuff ever dreamed up by the mind of man...YECCCCH! And 3 glassfuls yet...UGGH.
I drink apple juice the whole week beforehand to soften the stones...that's the easy part. When I get back from vacation, I think I'll do another.
I've adapted Hulda's method though and do my first Epsom at bedtime and then my second at 5AM....I am leary of three doses of Epsom salts and THEN bed because it is too fraught with risk...if you take my meaning; mattresses are too expensive!
I'm SURE there is a considerable drop in serum cholesterol afterwards, but which fractions and for how long, who knows? Maybe somebody on the major FLUSH site has done some work on this but I've never seen any info.
I guess Stumper could test for us since I think he's the only one with the CARDIOCHEK.
