Hi again pms
When desperate I use Lindt 90% cocoa chocolate, it is a bit of an acquired taste but it satisifies and has about 14g carb in 100g chocolate, I have found that 2 of the squares with about 3g carb don't do any damage to my BG. I have read some people say they melt it and dip strawberries in it, other people have said that they can eat blueberries, some cream is low carb and so you can have some fuit and cream
I have read here about a sainsbury's chocolate but I don't live near a sainsbury's to check it out, perhaps somebody else can help you on that one.
There has been a lot of talk on a thread here about the hartley's ready made jelly's, and ways to use them - I can't eat them as they are not vegatarian, but there are sugar free jellies out there.
Be carefull with yogurts as some of them are really high in sugar, even the lowest carb veggie ones I found effected my bg, though some no veggie ones have lower carb amount is in them.
But you will find that the less you eat the less you want to eat, chocolate is addictive and you will find it easier as time goes on.
