erectile dysfunction
"I have tried both Viagra and Cialis. Both have their pro's and con's. I get a better and more constant erection with Viagra. But it took over an hour to start working. The 10mg dose lasted about 4 hours but there was some residual effects afterwards. Cialis started working after about 30 mins and it really carries on for a good 24-36hrs, but the quality of the erection wasn't as good. I suffered with the snuffles with both. I got a headache only with Viagra but it wasn't a bad one though."
