The VA does not provide Viagra. Not routinely, anyway.
They will give you a script, but you have to take it to a pharmacy and buy it yourself.

It beats fading away.
And these "medications" are covered under the new prescription drug welfare program that kicks in soon. That number will be going up, if you'll pardon the expression.
It is estimated that more than half of the people using Viagra, Levita, etc. are doing so recreationally, rather than for true erectile dysfunction. As a doctor friend of mine once said, "It works even better if you don't need it."
