Sugar addiction

I'm halfway through the book Sugar Nation by Jeff O'Connell. It's an interesting read for those with a family history of Diabetes. It's an interesting read for those without a family history of Diabetes as well.
I happen to be one of those people with a family history of Type 2 diabetes. My father is a Type 2 diabetic. Although, he hasn't suffer the extremes of having a limb amputated like Jeff O'Connell's father, he has had triple bypass surgery a few years ago. He also suffers from neuropathy of his feet. He is on his path to other complications of diabetes as he does not follow a rigid diet. He also suffers from a sugar addiction.
I have read several other books over the past year regarding nutritional advice and 'fad' diets. These include the Paleo Diet, Atkins Diet, The Zone, The Primal Blueprint, South Beach Diet, etc. I have tried several of these 'diets' some with success and some without. I am not grossly overweight (6' 195lbs) but I fret over the future of my fate with primarily diabetes.
Does anyone else find it hard to not fall off the wagon?
I tend to believe in the 'low carb' way of eating. By this I mean getting my carbohydrates from primarily vegetables and a little fruit. This means staying away from grains and sugar. I struggle with Ice Cream. Who can resist a bowl of ice cream? The problem I have is I can't just have a small bowl, I need like 3 bowls!!! This is my drug. Sugar. It takes all my will power to resist. I can do well for 2-3 weeks, then BAM! I go on a bender.
Jeff O'Connel has described his life in the fight against Type 2 diabetes. I am going to describe my fight as well as  review more books and journal articles that discuss this way of life---that is---eating healthy via veggies, meats, nuts, and a little fruit.
Stay tuned
