First I had some blood work done and then I had to get an ultrasound. The ultrasound is how they determined I had at least 5 stones. Of course they didn't tell me the size or offer any further information, but what can you expect when all they want to do is refer you to a surgeon? Anyway, I will definitely report back during the flush. I hope nothing bad happens. I am so scared I will vomit the drink back up…I hope I can get it down and keep it down…
