Another sugar addict here. I had to remove ALL sugary foods from my house, if I don't have them in the house i can't eat them. I usually get the sugar cravings at night watching TV..... I've been getting on my exercise bike for about 30 minutes (I keep my exercise bike in the living room), telling myself if I ride for 30 minutes I can get something to eat after. Course the only thing I want after is Water. :-)
What I am getting at is the addiction is habit based (aka head hunger) so change the habit. This won't work every time, but its a start..... do something 3 times and it's a habit. Good luck and don't give up. You can do this!
