There's a desperate, wishful-thinking part of my brain that thinks, "Just 10 more minutes is all I need to eradicate this unpleasant sleep inertia!", and it overwhelms all reason.
I have my alarm clock in the adjoining room; it goes off, I hit Snooze once, crawl back into bed, then eight minutes later I get up and dismiss it again. As a result, I have about eight minutes to linger in the border-lands of half-awakeness, think about any dreams, and ponder the coming day. It's more pleasant to wake up gradually like that than to transition from sleeping to "awake and trying to accomplish things."
Then it's off to boil water for coffee. and I leave Snooze on for a while to remind myself of the passage of time in the morning, so I can make sure I'm out the door in time to catch the train.
I suppose the key is that the Snooze is not so close to the bed that I can press it hassle-free.
