The beast will always argue that the benefits exceed the cost. Just read around SR, and you'll find folks who are still drinking despite disastrous consequences. It's an ever-receding goal post, and the beast will never concede. When i quit, the benefits still outweighed the cost, or at least that's what i thought ( or my beast thought).
Calamities were a big one for me, and i have to admit that when i first quit, i may have reserved a contingency for calamaties, deep in my mind. However it didn't take all that much sober time for me to understand that I can bear calamities far better than my beast would have me believe. Beasts want us to believe we're weak, damaged, and unable to bear pain, when we are none of these things.
