I was so worried about it too! It was so simple. Hardest part was waiting in the bed in the hospital room.
Doctor was about 45 minutes behind as it is so that was the only hard part.
Once I got into the surgery room, they made me lay on my left side, made me gargle this nasty nasty nasty awful stuff. Then had to swallow this huge 2 tablespoon stuff, was the consistency of honey. That was the worst part. I dont remember anything, I was out like a light. Woke up in recovery and was fine. Just felt high from the drugs.
