Pepsi Max is the best!
Yeah, cold turkey definitely doesn't work! One of the main reasons I got Baby in the first place was so I could take her for walks to exercise myself!
I'm on weightwatchers, I lost 11lbs before christmas but then put 9lbs of it back on again, now I'm back to square one it seems but I'm only looking to lose about a stone
My best suggestion is pasta and sauce. I use like, two handfuls of pasta, with half a tin of chopped tomatoes and some basil - instant healthy meal! And so tasty

I'll thrown in a mini pepperami as a treat, only works out to about 6 points (you're allowed about 20 points a day) and it's so filling!
