I'm addicted to caffeine. My university has a meal swipe program which equates to ~6 bucks and you can use 2 a day. I eat one big meal from the 'all you can eat' cafe, then get 2 energy drinks for the morning and afternoon, and just have ramen for dinner or sthm.
I currently have 3 spares because tbh I'm kinda getting sick of redbull. Idk what else to spend the meal swipes on because if you don't use them it's just wasted money
