I'm reading the Sweet Poison Quit Plan too, sugar is my biggest, biggest weakness - I knew that for ages, but this book is a real eye-opener.

Artificial sweeteners I only use when i have to, I have gone cold turkey in my coffee, no cordial or juice at all, and diet soft drink only when I really have to. That stuff is not good for you either, but I have to break a cycle first, you know? Then I will kiss all that good bye as well.

You can get a no added sugar, low fat icecream (but it is Peter's, which is Nestle )

I am reading more & more labels above all, it's amazing what you don't realise you are putting not your mouth (well it was for me anyway ;p)

Also portion sizes, I have huge protion sizes & this is actully the hardest thing for me to cut down, not what I eat but how much of it.

ETA - re the sugar - I had done really well at cutting it out, but after a yucky couple of days I slipped up... and it was AMAZING how much my want's / cravings for certain foods reappeared, like nothing had ever changed.
It is so so true that after a little while off it you won't miss it as much, and equally true that if you go back, the desire for certain foods will reappear.
