Unfortunately, I too am one that had a Colonoscopy done last year. I am 35. Have had many gastro issues and I would have to agree with the lot of folks here that the prepping is the worst. They asked me what flavor I wanted in hopes that if I picked Lemon that it would taste like sprite. Well, it smelled like pinesol. I should of used a otc laxative lol. The procedure is nothing, if you are sedated. I was. Thank god.. The other part that did bother me , was there was a room full of medical students along w/ the doctor. A total of 8 people. I said you got like 2 mins to knock me out, because I feel vulnerable!! The dude came in and administered the med, and bam I was out. Best wishes to you!! it will be ok

Good luck
