Just had my scope on Thursday, prep was low fibre for 3 days before. Then clear fluids the day before and start the prep at 6 pm that night. Do only half the prep and then the rest the next morning at 6 am. I really hated the Colyte. My GI says I can try Pico- Salate next time as the Colyte makes me nauseous. I tried keeping a bowl of peppermints beside me and when I finished a glass of Colyte I sucked on one. Others have tried a lemon wedge.
Prep worked and scope was fine. Glad it's over. The prep is the worst part.
Good luck!
