erectile dysfunction
"I'm a 31 year old male. Physiologically healthy but with a whole load of stress and anxiety. I've suffered from erectile dysfunction since becoming sexually active.

Viagra was a big help but even at a low dosage I found the side effects intense, nasal congestion and headaches, often so intrusive they ruined the sex.

I've tried Cialis a couple of times now. At a dosage of 20mg it keeps me in a state of almost constant arousal, complete with spontaneous erections at embarrassing times, for 30hr . My dosage is obviously way too high and I will lower it but at this high level I have suffered no side effects, amazing! The sex is very natural, I am really very impressed."
