I feel your pain brother.
The last colonoscopy I had, for the prep I did the pills. It's something like about 60 horse pills and you take 6 of them every 15 minutes with a big glass of water and also drink a lot more than that during the day.
HOLY HANNA !! before they kicked in and "stuff' starting coming out of me, I did think for a little while I was just going to explode before they started to work their magic.
I have to have one again the first part of 2015, oh boy I can hardly wait for that. I'll most likey do the pills again, oh yeah, they are close to $90.00, that alone almost made me crap myself when I went to pick them up at the Drug Store.
All in all they cleaned me out better than the liquid did a few year prior to that, 3 years ago.
