@Symphonic: I guess we could try to recreate the conditions of the first measurement but there is no way I will be drinking Everclear in a while. That drink is very dangerous.
You could literally do it once every two weeks; unless you seriously drank to excess, giving yourself a 2.5+ BAC, you won't die. There's a total difference between "feeling like you'll die" and being on the brink of physical death.
As a follow up to everything:
My friend has the idea that with alcohol being a blood thinner, it could have caused more blood to be pumped down there leading to the increase in measurement.
... You really need to not buy everything you hear. That's a stupid theory; alcohol in the blood-stream reduces, not increases, blood flow, no matter who you are, because there's not as much oxygen in your body. Also, it dehydrates you, well actually your body does in an effort to get rid of it, so your penis doesn't grow, it shrinks, and your body does not give blood to "extra parts" when blood is in short supply.
@cigarbabe: I thought the whole thing seemed unusual (the increase in size) and that's why I asked for opinions. I also wasn't thinking that it would grow my dick. But the fact that you say it prevents erections, I'm skeptical about.
Basically you know nothing of alcohol. Stop playing with fire.
[ Yeah, now you really have no clue; I thought you were an engineer... :/ I always thought those guys were well-learned. You just said, even in concurrence to your friend, that a blood thinner wouldn't cause erection problems. What a dope. ]
