I get the fear. I truly do. I think if you buy into that fear, you've got a bigger problem causing you to do that. I think the fear is the alcohol talking. You can't listen.
It's not something I'm currently buying into. I'm a much more productive writer when I'm sober. I was published online last year and I will be in a journal in the fall Addiction is not a terribly rational state. On days when I feel like calling it a disease I call it a mental illness. No one really wants to wake up hungover every day or pawn Christmas gifts for their children on December 21 but the thought pattern is that powerful. And it's not totally illogical to assume that if you exclusively or primarily do something drunk and are successful like Stephen King before his wife dumped a 30 gallon trash bag full of empty coke bags, nyquil bottles and beer bottles on his desk and forced him to shape the fuck up that the two activities are related in a way where changing one will affect the other. Fallacious reason, sure, but not exactly so illogical that the brain wouldn't naturally come to that conclusion. And when writers, artists and baseball players have stupid superstitions they know are stupid but do anyway, a thing that noticeably changes your behavior is much easier to shake than only writing standing up or on a typewriter or whatever
