What sort of things were you anticipating carrying, Pop?
I have an ileostomy so have to take enough bags and other supplies with me when I go travelling. This can take up a fair amount of space as I use deep convexity bags and always take one for each day, just as a precaution, even though I would not use that many at home. I would hate to be stranded in somewhere like Africa without enough supplies.
Having said that, the only time that I have taken an extra overnight bag was when I went on safari in Africa and my doctor insisted that I take intravenous injecting equipment and 2 litres of saline in case I caught a stomach bug on top of my Crohns and became dehydrated. He didn't want me in Nairobi hospital without my own equipment.
Fortunately, I stayed relatively well throughout and was able to leave my supplies in a clinic in Tanzania before I came home.
