Ok so, the real question is what would you do? And why are you asking?
My addiction is so sick that I used to the think of things like this....truly. Zombie apocalypse? Why aren't they all panicking, running around trying to find booze on the Walking Dead. Yes, I've thought about that.
Totally totally nuts. And also shows how bored addicts can be. So privileged. When a true life or death scenario occurs I hope I think only of the people I love and how to help them.
But until then, I'll just keep living my privileged life where examining my navel is even an option. In much of the world, it isn't.
