My guy employs a lot of the above strategies as well --

Instead of parents, go digital. :P
What is something you tend to always have with/on you? A phone? Tablet? Wallet? Watch? Put them to work.

Alarms and synced calendar type stuff do wonnnnders for him.

Some of the new smart watches coming out these days look awesome - maybe having the reminders attached directly to your body could benefit? They link directly to your cell phone or tablet and feed it straight to you. (I just read a thing about "pebble" that's 80 bux or so for basic stuff, but I don't know anything other than that.)

I'm talking just basic reminders for what time it is, too. This helps my sister too - she has different alarms that sound off that are simply for the lunch time, evening, and time-to-go-to-sleep/wind down, just to keep the whole day in perspective.

It really sucks staying on a new schedule, but if I could push only one opinion, I'd say to stick with a rock solid wake-up and bed time. Especially bed time. Ever since we started doing this, just basic functioning has just spiked. Also, it just sets a tone of order at the beginning of the day, and the peace of expectations at night.

(Somewhat of an aside, but the youtube vid "Should You Use the Snooze Button?" by asapscience really sealed the deal on this resolution).

Can't explain how cool the sleep schedule thing is. I thought it would take like a month to get used to too, but it actually took about three days.

Regardless - alarms and more alarms, I guess!
