Yeah, when I do use alcohol, I make sure I have other liquids with me. Usually my friends and I will buy the day old donuts at Walmart or something and a few gallons of water. I'm pretty careful because I want my "escape" but I never want to end up in a hospital as some of my friends have.

And with the SI thing, it doesn't matter too much because I have enough other injuries (scars from other stuff including burns) That people really don't think twice about it.
