Had it about 10 years ago, it was the sickest I have ever been in my whole life. I lost 11 pounds in 3 days, coughed up blood, 105 degree fever, the works. Make sure you follow up with your doctor after antibiotics are through, I did not do this and it came back. I was almost feeling normal again after about 3 weeks, it took me about 3 months to get my wind back (running, martial arts, etc.) to where it was before. It is no surprise to me that in excess of 50% of pneumonia cases resulted in death in the days before antibiotics. It is no joke. Funny part was, I went in on off hours to my doctor's office, he wasn't in so I was seen by another doc who does not know my (former) profession as a deputy sheriff. When he asked me if I had been around any sick people, I told him, "you know, a few days ago I did have this filthy prostitute in my car, she was coughing a lot". He was stunned into silence until I realized how it sounded and told him I was a cop, and the contact was a "professional" one. Then he laughed his ass off. Get rest, drink ridiculous amounts of fluids, eat yogurt to counter antibiotics killing all the good bacteria in your gut, and you will feel better soon.
