looks like this would be a great team for you! www.sparkpeople.com/myspark/groups_individ
(there are also a few others dealing with sugar addiction!)
i usually try to drink an herbal tea when i have a sweets craving, or have some fruit, a small piece of dark chocolate and some milk, or a bunch of raw veggies (even though that's not the same, you can eat a TON).
good luck on your journey and welcome!
