A member asked:

What time should i start taking my bowel preparation on the day before my colonoscopy procedure?

3 doctors weighed in across 2 answers

Late afternoon: The effects of the bowel prep usually start about an hour after you begin and may last up to 4 hours (sometimes 6) so you can time the prep from there to allow time for sleep.

Maybe: You should follow the directions provided to you by your endoscopist and follow them exactly as instructed!
