Have you ever drank or eaten anything to the extreme, and never consumed it again?

Willworkforchocolate’s question http://www.fluther.com/102475/when-it-comes-to-liquors-which-is-your-ultimate-favorite/ got me thinking. I once had so much tequila, I never touched hard alcohol again. That was many, many years ago.

Have you had a terrible experience with food or beverage that has kept you from consuming it again?

Please divulge your horror story.
