I will grump! I went back to the doctor, still feeling crap after a week of antibiotics, and he said at the end of the course I can expect to feel only 50% better, it'll take 6-8 weeks to fully recover, and then told me off for expecting to be better quickly! "You have pneumonia, it's not a cold! A century ago this sort of thing regularly killed people!" Then he told me I'm not well enough to travel, so I have to extend my stay and not go home this week.
