erectile dysfunction
"Suffered with ED for years.  Had slowly gotten worse to the point of zero erections.  My Urologist prescribed Cialis.  The first time I tried it results were poor a few flacid short lived erections.  I called my doctor and he said try again as it might not work the first time.  The second time was fantastic.  The second time almost as good as the first.  The third time poor results only one erection capable of intercourse.  The fourth time even worse, fifth time nothing at all.  Switched to Viagra on Dr.s suggestion.  Cialis side effects were moderate headache, moderate back ache, stuffiness and sinus pressure."
