I have a sinus infection. My doctor prescribed a 50mg (5 x 10mg tablets) dose of Prednisone once a day, along with an antbiotic (Ciprofloxacin HCL) . I am on my 3rd dose heading into day four. I cannot sleep at all and am concerned about the lack of sleep, starting to feel strange mentally. My questions are If I stop taking the Prednisone today, cold-turkey, will I suffer any extreme side effects? or is 3-days/doses enough for it to matter, if I stop taking it now? FYI, I have no previous health conditions (other than my sinus infection) and never take any type of drug.
