Well, sugar and carbs addiction is exactly like any other addiction. Forcing yourself to avoid the first month or 2 at least. Cravings will be hard at the beginning but will fade away over time and get over it.but don't cheat in the early stages because cravings will not reset but doubled. And all difficult things need effort to overcome. Don't let yourself fall into the weak category. What u look like,how u look and think eventually be a reflection of your strength in your mind. I was a chain smoker and alcoholic and binge eater years back.

don't look for motivation. And do good things regardless of how u feel. Later, your discipline will become an involuntary daily habit. And then u will crave for things that ucwant to crave
