Sounds like a match made in hell right? I have to do a colonoscopy prep on Monday/Tues and Tues is fluids only with Picolax. One sachet at 8am and one at 4pm. BUT my DD has an end of term special assembly surprise for the parents that has been in the diary for ages. My DH can't go. Do I risk it? It is at 3:10. Don't particularly want to s**t myself at the school, but would hate to miss out, she is only teeny and it would mean the world to her if I was there. Would everything effectively be cleared out by 3pm ready for my next dose at 4pm?
