Ramadan Kareem to you too, Greeker. And good on you for choosing to fast for the month, for your own reasons. If you are taking local practice as your model, then fasting includes no water, or smoking (or sex!)

If so, I cannot see that doing without water during daylight hours can be considered 'healthy'.

Are there any medics out there who could comment on the physical (as opposed to spiritual) aspects of this?
