yes, horribly so! The last scope I had it was 4 days before I just couldn't take it anymore- my GI recommended Milk of Magnesia, which worked like a charm. No cramps, spasms, pain, gas, etc- just big soft bm's. I highly recommend it! It's funny, we complain about
going all the time, but when you can't go at all, it's just as bad- you get so uncomfortable.
