benign prostatic hyperplasia
"I started taking 5 mg Cialis daily because of bothersome BPH during the day. (I did not have problems during the night.)  After only a couple of weeks, I was better, and in less than 2 months, BPH was not a problem.  I do have a somewhat stuffy nose occasionally, but this is minor. I consider myself fortunate to have seen BPH advertisements on television because the ads prompted me to ask my doctor about Cialis."
