Earplugs!! I sleep like I'm in a coma using them. Set two alarms, buzzer on the clock and crank the volume on your phone. Use a wake up call too if you need it. I've read people saying they're afraid of sleeping through their alarm with earplugs - I am a pretty deep sleeper and I wake up with no problems.
Don't exercise too close to bedtime.
No caffeine within five hours of sleep - seven is better for me; caffeine affects me more than it does most.
NO NAPS. You will jack yourself up hard if you take a nap.
Try not to argue with the significant other within three hours of bedtime.
And be consistent. Lights out eight hours before your alarm.
I am a naturally late sleeper. On the road? I prefer mornings. I get my seven to eight hours every night and I'm good to go.
Going to bed at 730-8 takes a little discipline but you'll be much happier if you do. The first day usually sucks - after that it's smooth sailing.
