Just to add my 2 cents. My wife pushed and pleaded with me to have the procedure done and I just absolutely dreaded it but finally gave in after running out of excuses and scheduled an appointment. After doing it I wondered what the big deal was. I would rather do that than go to the dentist. My experience was as follows:
Drank the stuff that tasted like water. Was told it was terrible tasting. It wasn't. Watched TV while the stuff worked and had to get up a lot more. It was like channel surfing without a remote. Went to the hospital in the AM they put me under and woke up with the procedure complete. Went to restaurant to eat. Wife drove. Did some shopping in the afternoon. Went out for a nice evening meal. Went home and slept very well knowing I am healthy, at least in that department.
