You sound a lot like me. I have done 14 flushes now. candida is long gone, but some digestion and pain symptoms return with a week or so of my flushes. From what I understand, and have been told repeatedly, once all stones are gone, your recovery should be more longlasting. this also assumes that you have addressed the issues that led to the stone formation in the first place. for these issues I recommend reading Andreas Moritz 's two books "amazing liver cleanse" and "key to health and rejuvenation". they will help you understand how you can change the factors that led to stone formation.
also, give yourself time. don't push to hard. find a nice pace and work forward. don't worry so much about the day to day symptoms. they will eventually pass.
