I have had ed problems for the past 10 years. I'm 42 and have had to resort to taking viagra which works almost every time.
I take antacand for high blood pressure once a week. When I was younger I took more powerful hb drugs, but it seems my hb is becoming less and less of an issue as long as I exercise.

Here is my question. I wake up every night will a full erection when I have a full bladder. Why can't I get an erection during the day without taking viagra?
What can I do to get off the viagra?
