I was recently treated for bronchitis with a double-dose of the Z-Pack and prednisone. I am 48 y/o male - I ended the dosage last Sunday - Yesterday I got a headache that has not gone away and I was not hungery (did not eat yesterday), stomach ache, nausea (no vomit), and I laid down yesterday at 4:00pm and woke up this morning for two hours, then back to sleep for another 5 hours. - My normal sleep pattern is I only require about 4 hours a night and cannot sleep any more than that amount of time. Is this a withdrawal from the steroids? I was prescribed more than I normally am prescribed for the Bronchitis I get usually once a year.
