Have you ever fasted (gone without food and/or water for a specific purpose)? What did you fast for? Was it beneficial to you? Additional thoughts?

Ramadan has me thinking about it.

From wikipedia:
“Fasting is primarily the act of willingly abstaining from some or all food, drink, or both, for a period of time. A fast may be total or partial concerning that from which one fasts, and may be prolonged or intermittent as to the period of fasting.”

Fasting is a part of many religions, Eastern and Western.
