  Are you talking about a date with a girl or chemical reaction / treatment for a patient
  
  as for the date it does not take long, you can never guess a woman’s response (trust me there is no pattern here) …If it goes wrong …( you don wanna know what happens..u ll get to know it soon)
  
  as for chemical reactions and treatments…It takes mins to hours depending on the complication of the issue and if it goes wrong one things for sure a lot of time is waste and most likely you are in trouble…lol 😀
