Hi your question would sound better like this; Have you ever fasted in your life? What was it like? I usually do a 24 hour fast with my students to raise money for charity each year. I feel a bit dizzy at the end of it.

I have done so. It's not something I plan to repeat. I did it to test my limits, and to get some idea of what it's like to be without food. Trying ramadan one year, I noticed that I found it very difficult to get any work done, and I was light-headed all the time. I also found I ate a lot at night, when the sun set. After 48 hours of (unbroken) fasting, I find it very difficult to think at all, and finding the energy to move from place to place gets rather hard.
