COPD
"Hacking deep dry cough woke me up in the middle of the night for days until I started the Prednisone taper yesterday.  Last night I woke once with a light cough, but easily went back to sleep.  I am taking  10 mg pills, 5 a day for 2 days, then 4 a day for 2 days, then 3 a day for 2 days, then 2 a day for 2 days, then 1 a day for 2 days."
