Hello @kathy49, I second what @gingerw said about colonoscopy prep. I will be 82 in a couple of months and swore after my last colonoscopy at 78 I would never have another one but things change. After my annual checkup the topic came up again and after weighing the pros and cons with my primary care doctor I decided I would schedule one. My last prep which I thought was OK didn't work out very well so this time I have to take an advanced prep which involves the tasty liquid (yuck!) along with some laxative tablets.
