Hmm, I had my colonoscopy done just 5 days after the appointment was booked (someone had cancelled). It was 2 yrs. ago.

I don't recall avoiding nuts and seeds. But I did gear down to softer foods. I also had to drink a prescription based powerful laxative (or is it close to an edema?). Pretty awful tasting, but I did it every few hrs. Then had colonoscopy.

I was a given a photo of my colon...just gorgeously clean.

I would suggest you ensure someone takes you home. Don't drive. You'll be too weak.
