I DO have a related job and stress thing that's been helpful to myself, during sleep time:
In a stressful setting (at work), when tossing and turning at end of sleep time, (assuming you aren't doomed to respond to alarm clock madness), there is a technique for how to start your next day. In other words, for the transition you would need to make, to wake up, get up, and start your new day.
It works like this:
Suppose, as you've been glancing at your bedside clock, and must get out of bed soon, suppose you have been starting to run the day's tasks ahead, in your mind....Messed up this, and messed up that. Now, as all those thoughts circulate, what you want to do is WAIT for a positive thought and situation, like suppose a co-worker, 'Jim' has done a few really good management items at the job, and now this Jim guy is building a new manufacturing fixture, or something...
That's it: that's the point in time, (laying there still in bed), that you should start up, rise up and get moving, on that positive thought. Doesn't have to be spectacular, just maybe a little smile, and thinking positively, " That Jim really is going to make this organization move up to a better positioning, in marketplace". Whatever, but you get the idea, just use some minor positive aspect, as a sort of trigger, saying 'Ok that's it, I should get out of bed, now'.
(Starting day grumpy isn't going to help).
