Atkins diet...does it really work? have you tried it? can u give me tips?

I put on some weight after an operation I had a couple of years ago that restricts my exersise (I cannot run) and as I work full time and have 3 kids I dont have time for any of that anyway...well I want to try the Atkins diet as Ive heard it is very good...I am 14st and would like to be 11 so i need to lose around 30/40lbs ideally for the summer to celebrate my walking again and to be able to wear shorts for the first time in my life(well apart from being about 6!) so what do you think and if its a good one does anyone have tips to help me? I'm useless at this diet thing and counting calories bla bla bla.....thanks :)
