thepominlaw - and I am sure that you can achieve what you set out to do.
I know of a woman who weighed in at 27st, she is doing Atkins and so far lost over 13st, secret is one day at a time, dont think too far ahead, plenty of support from those around you and you will find it here in the forum as well. We are with you all the way.
Where do you start? I think your first port of call should be Viv's Modified Atkins Diet, then look through the low carb recipes section for a lot of delicious recipes, most of them tried and tested by members before they are posted.
You can even have the odd chocolate treat, have a look at the Chocolate Paradise thread, also in the low carb recipe forum.
