erectile dysfunction
"I'm 66 and had a heart attack with bypass surgery 10 years ago.  Erectile dysfunction became a problem since being on a beta blocker and a satin drug since the heart attack.  Doctor cleared me for a test drive on Cialis and I took a 20mg dose for the first time last week. It give me a hard erection like I haven't had in 10 years, it was great. But the facial flushing and headache was kind of bad.  I'm thinking it was too strong so I'm going to try 10mg to see if it works with less side effects."
