Follow doc's orders as much as possible. Pneumonias have a funny way of lingering, or getting worse. Either way, you lose more time in the end than if you just baby yourself for a few days now. If the doc prescribed antibiotics, take the FULL COURSE, even though you're likely to feel better sooner. Otherwise, lingering bacteria may reinfect you, and you're worse off. Stay well hydrated, and well nourished. Your body needs energy to fight infection.
Get well soon!
