I have worked the Dupont Schedule for 2 years, so I can offer a little help.
-I stop drinking any fluids after 6am, no matter what. No caffiene past 2am.
-I agree with blacking out your room and I also suggest investing in a loud fan. Turn the cell phone off and stick it in another room. Also, if you get up to use the bathroom, try to make sure all rooms and routes to the bathroom are dark. if lights are on or come on, that triggers your mind automatically that it is time to be awake.
-Naps are your enemy
-I like to eat dinner at 730 then another small meal around 2am. I munch on snacks too. I drink a protein shake around 4am to 'eat breakfast'
-Working nights can add on the pounds so try to pack a healthy meal and snacks. Try to drink Tea instead of Cokes if you can. If you are looking for a cheap caffiene boost, look at HEB in the water bottle drink mix aisle for Spark Energy drink mixes(orange box size of deck of cards). They are $2 for 8 servings and have more caffiene than any energy drink or coke on the market.
