Best and most comprehensive hangover prevention regiment?

So basically I have a huge midterm tomorrow but I need to drink tonight to celebrate one of my brothers getting his dream job. What is the best regiment I can do all day to prevent a hangover to the best of my ability? Here is my current plan

Today: 1. 3000 calories today, 2000 of them from carbs, stop eating 2 hours before drinking 2. One Gatorlyte before drinking and one before bed 3. Two liters of water throughout the day and while drinking 4. Two B super complex pills, one zinc, and one vitamin c 2 hours before drinking 5. Only drink light liquor and beer 6. Asleep by 12am

Morning of exam 1. Wake up 6am 2. Puke and shit 3. Chug another Gatorlyte 4. Chug energy drink with 200mg caffeine and taurine 5. Shower 6. Adderall and advil 7. Eat a bagel 8. Sip water 9. Take exam at 8am

If you have anything else you can add, please let me know!
