I helped my husband through his first flush on Friday night. I was happy that he decided to do it and I was hoping that he would get some stones out - I was afraid that if he didn't he would never try it again. Needless to say, I was VERY surprised by the size of the stones he did get out! They were huge! He isn't one to really internalize and pay attention to how his body feels, so I can't get him to tell me if he feels any better after one flush. He does think he should do more because of the size of the stones that he got, so in a couple weeks we'll try again. I've posted a picture of his stones: Tiffany
