I dread this coming weekend. Missing that hour of sleep, and resetting my internal chronometer and circadian rhythms, get more and more difficult the older I get.
But I've found a method that helps with the transition.
I don't do it all at once--notice that word transition.
Starting with the Monday before the change, I set my alarm clock 10 minutes earlier each day. I don't actually get out of bed, I just let the alarm clock wake me. On Friday, when I'm waking up almost an hour before I normally would, I might even attempt to go back to sleep--but at least I've awakened early. By the time Sunday rolls around, waking up early is old hat--and it's so much easier to adjust 10 minutes at a time than it is to jump into the entire hour at once.
Try it and see! There's still plenty of time left.
And now, good night!
