Thanks for the advice; I hadn't thought of the full moon as being a good time but it sure makes sense considering the moon's effect on the human body so I am excited to try it again then! I'm glad to know the pain isn't unusual. I was worried because I could find no other postings that mentioned left side pain. Most seemed to have right side pain. I was starting to worry some other organ was acting up on me :). I did take pictures but they aren't developed yet. Took my stones to my general MD to send to lab for analysis but she just looked at me like I was nuts:). Didn't much surprise me-- doctors don't make as much money when you help cure yourself:).
