Erectile Dysfunction
"I have taken up bike riding on a serious note of late.  I have at the same time been having increasing difficulties maintaining an erection. I am 55 with heretofore an active sex life.  Over the past two years the dysfunction has become progressively worse. Today I used this medicine for the first time. I have had a prescription for a month. The directions call for three 20 mg pills one hour prior. I took one as a first try. I and my partner were very pleased with the results. 
The resulting erection  was normal natural for a man my age. I will report later if going up in dosage changes anything. But I am happy with the results.

Side effect sniffles for a half hour."
