had a chest infection a couple of weeks ago, woke up one morning, congested with rust colored phlegm, and a little blood (from violent coughing). the doc gave me amoxicillan, it seems to have cleared the chest (still have a little bit of sputum coming up, mainly in the morning). but the real problem is I wake up through-out the night: sweating, rapid breathing, dry throat. Fatigue and exhausted all day.
