Davo,
I do wish you the very best of luck with your surgery, and glad that you have decided to go ahead with it, even though you're healing. I get ups and down with mine and it's very frustrating wondering what to do. I have really procrastinated for 18 months, but am at least planning a trip to NY now and will have a capsule colononoscopy (terrified of the other type) and a consult with the AD doc.
Anyway, as above, all the very best with the surgery. May you sail through it and be all well for your impending wedding (if I am remembering rightly that you are getting married relatively soon).
