The auto-snooze has always worked for me. With the alarm-clock extreme I set it for 5 seconds where it gradually gets louder. Something that helps generally is to practice. So whenever you have some time to kill set your alarm to go off every minute for the next 5 minutes and auto snooze. Then train yourself not to move, and to not get excited when it happens. Just lay with it going off and put the idea in your head that you won't move and will stay calm. I think it's called a mantra. Anyway that's what I've done. And although I just recently started doing it again, when I used to do it a lot it would bring on lucid dreams almost every night. And some nights I'd have 5 lucids.
