I was absolutely dreading it having read some threads on here about how awful it is and having heard the same from friends and relatives.
laxatives: I opted for picolax over moviprep because I was worried I wouldn't be able to stomach a large volume of laxatives. It was a reasonably pleasant orange flavour and easy to drink with a straw in about 4 gulps, with a quick drink of juice between each gulp.
bowel prep experience: It took about an hour to kick in and then lasted 1.5hrs with some further lighter episodes a couple of hours later. It was really quite civilised, I kept thinking worse was to come but I've had worse stomach bugs to be honest.
colonoscopy: Nothing to say, no pain and all over very quickly.
recovery: Again, nothing to say. No pain, no nausea, able to eat immediately.
I hope this helps anyone who is worried like I was. I credit the positive experience to following the dietary, fluids and laxative instructions to the letter.
