Drinking lowers the inhibitions. Note that I didn't say "drunk", just "alcohol". Much like viagra, this will be taken by people who don't actually have the problem. And the side effects are pretty terrible. So yeah, alcohol probably will work just as well for most if not all people. I think we're way too willing to prescribe things to people.
And besides, it was a joke. I do that. Occupational hazard. Not always funny, but almost always joking.
