erectile dysfunction
"Excellent drug. No serious side effects with 20mg repeated after 72 hours. Slight indigestion but nothing more. Effect lasts about 36-48 hours. I find myself having erections 6 days later but this could be because I gave up smoking over 1 year ago. I also use Viagra with good results and no adverse effects. Great drugs but consult your doctor before taking these medicines. I am 57 years old and have no serious health problems. I am certain that my erection problems were caused by smoking."
