I hope there is hope for you! I have a 2cm stone myself, that's been giving me a lot of problems. When I heard about gallbladder flushing I was scared at first because I was worried the stone might get stuck. But in the last month I have read a lot of different people's stories, and a few of them have reported flushing stones as big as 2.8 cm and even bigger. Someone on here just recently said they flushed one almost 4cm large!!
So, I'm really hoping there is hope for both of us! I am determined to get the little rodent out without surgery. I did one flush the other day with poor results (I realise now I was extremely dehyrdated). So I've decided to do a parasite cleanse first before I try the flush again to try and maximise my results.
