"Best results for me if I take the 50 mg dose before eating anything.  After a meal, I find that Viagra does not help me get an erection for hours, if at all.  If taken on an empty stomach, it works fast.

I also get flushed, but this tells me that it's working.  I get occasional headaches from Viagra, but the side effects are well worth it!"
