This is a super obvious one. We all know that you should drink water when you’re drunk. I think I even learned this in school or from my parents or something. We'll blow through this one, but I’ll talk a little about how it works- hopefully the knowledge will help motivate you to actually do what you know you should.
Cause #2 – You Haven’t Eaten
It takes a lot of energy and effort for your body to process alcohol. Lots of people go drinking for hours and then don’t eat anything until the next day. No food for a long time but lots of booze instead leaves your body without enough energy to process the alcohol. Then the next day your body is drained of nutrients and run ragged from the effort. The end result- your head is fuzzy and you feel like shit.
Cause #3 – You Drank Cheap Alcohol
Cause #5 – You Had Bubbly, Sugary and/or Caffeinated Drinks
These things won’t directly give you a hangover, but they do a lot indirectly. Lets break it down.
Lastly, if you are anything like me, sugar and caffeine get you jacked up and you do ambitious (stupid) shit like order lots of shots. Again, you are putting lots of alcohol in your blood stream. Sugar and caffeine also dehydrate you. Sugar + caffeine + alcohol = Three pronged dehydration action.
Bubbly drinks cause more alcohol to enter your bloodstream (opposed to get broken down). The more alcohol that enters your blood, the worse the hangover. So, if you want to get drunk faster and easier, but feel shittier the next day, drink drinks with bubbles. On an empty stomach.
I am sure that there are more but these are some good causes that are also super common.
