I find the Ramadan rules confusing. There is no way I can go all day without water, and I know women are exempt if "indisposed", but how can they tell? I also read the eating & drinking in public is illegal in UAE during Ramadan, and then that it is not expected if not a Muslim.

I am totally confused.

Except about covering up. I'll do that anyway or I will be burnt to a crisp (I am very pale).
