Make the trait 'addict' less punishing

[The Grim Sleeper]

Looks to me like a result of 1's motives system, because that system has a bunch of other unfun mechanics like alcohol dehydrating you, so this wouldn't seem too out of place there.

Iirc, all my hydration/nurishment/etc were still in the green. I did get an out-of-nowhere O2 alert, and that was probably what did me in. 

Under what circumstances does the motivation system do that? And is that a bug or a (serious) feature?
