Hangover kit

I need your help please! I am getting married in September and at the end of our reception we are planning to send each of our guests home with a bottled water and a little hangover kit. What would you want for hangover relief? We were thinking…

-Gum

-Granola bar

-Advil or Tylenol?

-Tums or Pepto?

-Pedialite or Liquid Iv?

Any preferences between the options? Anything you think is unnecessary? What would you appreciate having that is not listed? Thank you!!
