Bowel prep for colonoscopy -- keywords and MeSH

I'm posting this strategy because I don't want to have to start from scratch in the future.  It's a first attempt based on just a couple hours work.  In this case, I intended to err on the side of specificity rather than sensitivity; I wasn't working on a systematic review.  Most results retrieved are relevant, but some relevant results are almost certainly missed.
