Why not try having a daily health checklist? It might help you stay on track. Here's a sample:

DAILY HEALTH CHECKLIST

• Drink water. Lots of it.
• Eat vegetables often, throughout the day.
• Move/use/exercise the body; try to work up a sweat.
• Take a moment (or two) to stretch.
• Walk as much as possible. Take the stairs to keep the legs strong.
• Have good posture (try to not slouch).
• Getting 'enough' sleep is very important. Try to sleep for a decent amount of hours.
•
