I downloaded an alarm app for my phone, yeah going across the room and back to bed doesn't help. This alarm forces you to solve math equations before it will turn off, you can select the amount of problems to solve and the difficulty of the equations. There is no snooze option, just loud obnoxious alarm. Fun..no! Works... Yes if you make them hard enough that you really need to think and a few or more so you actually wake up.. Ahh too bad . Of course you could still go back to bed by choice, as far as I know there is no robots around yet to help us out here. However this solves the faltiness of the snooze cell phone issue. There are a lot of alarm apps like this around.

Like PD I also use several alarms set to varying times. Yes it is annoyong but I have a problem hearing my alarm and the sound just becomes part of my dream. So far this has worked, have not been late yet.

As far as resetting sleep routine, always good to try. Some people naturally have a different sleep/wake cycle. There is a lot of info on rhis out there. If that is the case, most people will default back to their own rythm and have to keep trying to reset their internal clock. Hopefully that is not the case and resetting your sleep schedual would stick.

You might have to give yourself some bounderies about what your mind gets up to at bedtime. Like a "no philosophy" rule. Sounds silly but I did the same for science, philosophy.. Watching Dr.Who or Ted Talks or anything like that at bedtime.. Nope or I will never go to sleep.
