For the past 3 weeks I've been totally off sugar, except for an apple or grapefruit each day. Its not a big deal since I stopped using it in coffee or tea a couple of years ago - that was the hard part.
I've always found that if I have a craving for anything I should drink a glass of water. It tends to stop the craving and clense my system in the end. Not keeping sweets in the house is a key component of this too.
