If I was muslim i'd cheat and sleep during light hours and be awake at night (great if you don't have a job).
Couldn't bare not eating food for a period of 16 hours is it?
I fasted for 3 days once. Your hunger diminishes greatly after the first day. One thing I learned from fasting is that probably 60-70% of the food you put in your body you don't really need. You eat more though because a lot of food, especialy fast food/junk food is addictive.
