I'm a sugar addict too
I take no other drugs, but sugar is the hell. I tried so many times to stop it, but failed every time. I stopped smoking three years ago and I must say, it was difficult, but not nearly as difficult as leaving sugar behind.
I really don't know what would help you, level1, except for not eating sugar at all anymore. I also found Deepak Chopra's books about addiction to be a great help.
Good luck to you!
