Polyethylene glycol 3350 with electrolytes
"Had to take in prep for colonoscopy. It tastes awful, thick salty, lemony water. It really helps to drink through a straw, I had to put cordial in it in the end to get through it. I had the split course, after starting at 6pm and taking 2 hrs to get the first litre down all I could think about was having to drink another litre at 8am.

Didn't start to have bowel movement until about an hour after I'd finished about 9:15pm, once I started I was on the toilet for about 2 hrs, not painful and watery straight away. Was up in the night about 2am for another hour, but that's not unusual for me. Just started the 2nd litre doused in cordial. Will let you know how I get on"
