yikes Well done on losing 9lb! Another 5lbs, and that's the first stone gone, and a fifth of the way to your goal - brilliant!
Can I recommend India Knights and Nerys Thomas's Idiot Proof Diet (bright pink book) for low carbing? Can be bought v v cheap on Amazon, and can also buy a cook book that matches the diet. I found the book friendly and encouraging, and the diet easy to follow.
At beginning of this year I had 7 1/2 stone to lose, and so far have lost 3. Would have been bit more but haven't stuck rigidly to the very low carb during last 2 months (difficult personal circumstances), although still minimal carbs and haven't gained anything. However, I'm restarting properly again in September, and am confident I'll lose another 2 stone by christmas.
There is a great, supportive, funny, informative forum called pig2twig, which is fantastic, and free 
I've never successfully lost weight before, and it's been completely wonderful.
I didn't really notice a big difference in the way my clothes fitted until I'd lost about 20lbs, so you'll be taking in those belts soon!
Concur that sugary foods and drinks are full of carbs, and diet coke can seriously stall weight loss. Anything ending in -ose is a diet buster on a low carb plan: glucose, fructose, sucrose; after all, that's what carbs 'do' - they are broken down by your body into glucose for fuel, so sugars are simply carbs fast tracked into your body. My weight loss diet consists of proteins and veg mostly, and 2-3litres of water per day. Sounds a bit dull, but I love it - there are masses of good recipes to try! Oh yes, and can eat cheese and add cream to things, yummy. I'm never hungry, and feel full of energy, with clearer skin.
