After I posted my last message, I got to thinking. Then I remembered. It wasn't bile that caused the burning. It was stomach acid being released to my colon. But I still don't remember what I did to cause it. Well, maybe these flushes will improve my memory. Last night, my first flush, was going well until I went to bed. Then about 45 minutes later I had to get up to go to the bathroom. I got up twice. I fell asleep but I tossed and turned all night. I hope this didn't stop the stones. I'm passing small light colored stones. I guess they're stones. So far no sign of dark colored things. Will let you know as the day wears on.
