I'd like to do this as well.
I have a very strict deadline - I have to look precious and be off-fast by Nov 11th - so I better start as soon as possible ;)
Stats would be as 66 kg and 156cm (I'm in Europe) and starting from tuesday - hopefully.
Of course I've tried to start it before and it's just not happening... I work part-time and I go to school - so my days are quite busy and I could fast - but I also have 2 kids and a husband and I have to cook for them... and that's how it always ends...
But I do hope it'll be better day tomorrow - because now I have company and I have made a tough enough decision ;)
It'll be water and herbal tea fast for me - I've heard it's the easiest to take.
