Surgery

I have done 5-6 Dr. Clark's Liver Flush and I still have horrible pain and vomit. I finally got an ultra-sound and I have very large and many stones in my gallbladder. So I will be getting my gallbladder removed. I am disappointed to have come to this, but I am tired of feeling awful. I also have inflammation in my gallbladder. Why did this flush not work for me? Someone told me that if you lose weight in your 40's, then you develop gallstone. Well, I did lose 35 pounds and I am in my mid 40's. Could this really happen?
