Hi, don´t worry about
the prosedure, prep is always the worse thing for me. I used to be given Fortrans (4l of liquid to drink over 4 hours) and couldn´t do it-max I could was about
2,5 litres, then I couldn´t carry on without vomiting it-which didn´t clear me enough.
This time I had liquid diet for 3 days + enema. Was that a torture ! Was cooking for family+sister+brother in law who were visiting at the time and could´t eat a thing
The procedure itself was fine, no pain. Good luck !
