I'm glad you're getting it done. I was a big girl and did both ends last Oct.
I goofed up and ate too long the first time, so they couldn't do it. The whole "process of elimination" was much better when I did it according to the directions.
The exam was a piece of cake (oops, sorry, hope you don't like cake!)

Of course, I was asleep, but there was just about no recovery time.
Good luck and have fun!
Don't forget to post the pictures!!!!
