Its easy to think that using work as a distraction (rather than something destructive like excessive alcohol or drugs) may be OK, but its really not. And most employers will more than willingly accept you working all the time.

Don't fall into the trap. Work is very important, and yes you will work really hard sometimes for time-sensitive things and on-call duties. But it should be understood that those things are anomalies, not something to be expected all the time.
