Pre-surgery, I always took some type of Cold medicine like the Alka-Selzer Plus/Aleve Cold and Sinus stuff that would help with my colds, but since surgery, I've lucked out and haven't gotten sick since then.
Orange juice was always good for me too (but now I can't have it)
When I'm sick, I do want to have my tissues with baggie for the used ones, my blanket, my books and my dog to snuggle with. I don't like soup, so when I'm sick I want good food that I can eat
