Four weeks ago I was admitted to the hospital. Feeling the effects of all the common symptoms of a CF exacerbation, it was time for a “tune-up.” My lung function was down. My x-ray showed some more marks than normal. My breathing was short and labored. My mucus production had increased. I couldn’t get through a night without waking up in a coughing fit. I was run down. My body needed a break. It needed medicine. It needed rest. It needed a tune-up.
