erectile dysfunction
"52 years old and was having problems keeping an erection or getting hard enough for intercourse, for about 3 years, although I could have a partial erection.  Doctor gave me 5mg Cialis daily and it works like magic.  I find it lasts about 36 hours.  I am harder than I have been in years and wake up with a really strong erection.  I have had zero bad side effects.  Before if could get it up for sex, I was definitely done for the day after one orgasm and sometimes the next day couldn't get hard at all.  Now I can go twice or three times in one day, if only I could keep the wife that interested!"
