I personally do not like enemas because I am scared of damaging something inside of me, just a personal preference. I would do a liquid diet all day and drink 2 bottles of Magnesium Citrate
My favorite liquids are gatorade and lemonade yummmmy!
I had my first pouchoscopy awake (no sedation at all) in July, it went great! Its definitely tolerable doing it awake if you do not have a ride I drove there and back home
