I had one just last Monday and have a post on it called "dread, Dread, DREAD".

I had to drink the EZ Prep. It is not so bad. Only one 12 oz glass and it worked. Be prepared to spend a lot of time in the bathroom. I had a tv table with laptop, books, etc set up and ready. I was afraid I would be hungry, but you are so focused, you don't really think about it.

The procedure itself was a BREEZE. Nothing to it.

In 52 years, I've never been put to sleep. I did have a problem with nausea and throwing up after my procedure that was caused by the anesthetic. If you don't have problems being put to sleep, you should be fine.
