title_body: Remedy for a coffee hangover?
upvoted_answer: It's probably a caffeine &quot;withdrawal&quot; symptom.
  According to WebMD
  
  If you stop taking caffeine abruptly, you may have symptoms for a day
  or more, especially if you consume two or more cups of coffee a day.
  Symptoms of withdrawal from caffeine include:
  headache
  fatigue
  anxiety
  irritability
  depressed mood
  difficulty concentrating
  
  
  It might be best to either reduce the coffee you drink during the week, or have coffee on the weekend too.
  To avoid my headaches, I choose to have coffee on the weekend too.
