You didn't do anything wrong.

The Tiger Balm will wear off and you're not going to die.

Please increase your fiber intake, if nothing else a glass of water with a tablespoon of Metamucil (or generic equivalent) every night. It'll change your life, I promise.

Also, if you're getting headaches, it's because you're straining. Using the fiber supplement will help you break that very dangerous habit. Consistent straining will lead to many problems in the future, prolapse being the most common.
