That is great that your doc wants to save you from gall bladder surgery. It is my understanding though, that if you keep at it, the sludge will go. I saw sludge go with my cleanses - but then I didn't have a diagnostic test to see if it was all gone. It really helps to do low colonics
some hours after you take the magnesium citrate, to see what is really coming out, I think.
My personal opinion is to never stop trying to kill the bugs. There seems to be no way to know for sure if you got every last bug or egg & the eggs can literally be inhaled as you walk around outside.
I have been doing maintainence daily for months & have felt no ill effects from that. Don't want to give them a fighting chance to regroup & repopulate.
DE has no side effects. If you are really low on the parasites
then you can combine the zapper & magnetic pulser & herbals, liver cleanse etc.
If it were me, to avoid the risk of too intense die off, I would do the parasite
cleanse first for a few weeks, then add the pulser &/or zapper. After a month, while on maintainence with the parasite
killers, I would then start doing Liver Cleanses
bimonthly. I would bet at least $5.00 you can get rid of that sludge, though it may take many months, but I'm not an expert or anything, just sharing what I have read & experienced personally.
Don't forget to use lots of Milk Thistle for your liver, & maybe eat liver tabs or, the doggie organic liver treats food I eat - Bellyrubs. (Don't laugh. Or not too hard.)
