I haven't had one but sending you good vibes for the prep, test and results. DH had one and said it wasn't that bad, he has trouble sleeping so a day sedated was nice. He had to have it to diagnose his crohn's.

My dad put his off and at 52 was determined to have Stage 3 Colon Cancer. After having a piece of his colon removed and six months of chemo he will be the first to tell you it is worth it. He will also tell you the prep sucks. I have to have one at 40 thanks to dear old dad but I will be doing it shortly after my birthday.
