The whole colonoscopy thing is a really really big deal for a guy...Expect to be on call as 'SUPER WIFE!'.. including providing all needed and appropriate 'deep-meaning' Umms and UhhHuhs at the rite moments... The process of preparation is truly far worse in my book than the actual testing... But, w/some folks the air/gas in the tract during the testings remains and will evoke protests.... Keep telling your self 'There ARE worse tests, ask Billye or Kmeb?'
I think it was about the flu, but recently, on the news or something was guidance about setting up a portable TV and books in the BR for the duration of the 'whatever'..not a bad idea, really.

We all live thru them...In the meantime, I'm betting you WISH you had a 2x4x' handy? That or write it down.

Web up the process, it's all the the prep before and how/what you do/eat after that keeps you happier in the long run...
During the fasting process, I had the absolute WORST craving for NUTS! The last thing you want before such a procedure!

I dunno, this may sound silly, but, in my neighborhood, many couples do evening walks at dusk. Some holding hands, some just shambling along, others really talking. I've not done it w/my person, but I've always found it kinda super sweet and well, romantic...Maybe you could get your guy moving and talking as well? It would be a start...Just don't tell about the romantic part?
