Has anyone ever taken an enema BEFORE they do the colonoscopy prep?

Has anyone ever taken an enema BEFORE they do the colonoscopy prep. If so what. Volume and type of solution did you use. Did it make the actual prep more tolerable. Would like some tips and insights.

Thank you, @Nullie, for asking this question. I have my first ever colonoscopy coming up in mid-August, and I’m wondering about the same thing.
