Your food advice is pretty terrible, drinking energy drinks and eating junk is a surefire way of either killing yourself or ramping up fatigue.
Here's some proper advice, make sure you're preordered and preloaded the expansion and get to bed at a time that ensures you'll wake up near midnight of launch.
Give yourself two hours to fully wake up, prepare your breakfast, lunch and dinner plus any snacks and drinks. Here are my personal recommendations:
Breakfast: Something with a high amount of fibre, my favourite is museli - weetabix is also popular along with shreddies and porridge oats. Fibre does two things, it slows the processing of carbohydrates and makes them a more efficient long term energy provider and it also fills you up. Whatever you do do not miss breakfast.
Lunch: Something along the lines of a chicken sandwich would be great, pasta is another option here but I'm saving that for my dinner.
Dinner: Pasta (with chicken cuz chicken is darn tasty)! Can be served cold and is still tasty!
Snacks: Fruit is good, yoghurt can help digestion and anything sugary is a no no.
Drinks: Water, water and more water. If you're feeling tired after a while, DO NOT DRINK ANYTHING WITH CAFFEINE. I can't stress this enough, caffeine will have you taking pissbreaks every 5 minutes. If you're feeling tired, take a glucose tablet or some sugary sweets like Haribo and energy bars are fine too.
One final piece of advice, take heed of your mortality. You are only human, make sure you rest appropriately when you need it.
