THEY BLOW. Just drank the prep junk, and waiting for the worst. I have to get up at 3AM for round 2. I'm guessing Friday afternoon and Sat I'll be doin a LOT of sleeping. And they are sticking a camera in "the other end"
Smart thing to do though. You'll get through it and hopefully all will come back with good news. Then you'll be glad you did it and can go another 5-10 years before the next time.
