Hi all just had my first colonoscopy and I can say it was a positive experience. The worst bit is only the prep drink. What I will say to make that easier is I fasted for two days straight and just had water and lemonade at times. This made going to the toilet not as bad as I didn't have to make many trips and my report said the bowel prep quality was excellent. If you're a woman that wants to wear your bra inside make sure you wear a sports bra as I had to take mine off as it had a metal underwire. I did experience a lot of pain mid way through but I chose not be sedated so that's probably why, I also have endometriosis so that always gives me pain too. Overall don't be nervous it's only 20 mins and youd rather be safe then sorry.
