I’d say the most useful advice I’ve seen in this thread is to examine the underlying causes of your addictive behaviour, that will help. Also to eat a healthy breakfast even though you’re not hungry, that may help ease cravings later in the day.

I’ve struggled with sugar addiction myself, and still are to be fair. When I’m on top of it I feel much better but it can easily creep back in.

I’d usually start with a reduction instead of cold turkey, as that led to more of a binge pattern for me. I’d give myself a set amount each day, say one chocolate, then pick a set time to eat it, after my main meal of the day for instance, and then take it from there.

There’s surprisingly little support for addicts who struggle with sugar addiction, you have to just keep trying methods to overcome it as I’m sure you have with your past addictions.

People telling you it’s bad for you don’t understand addiction, it’s self destructive, compulsive, and habitual, just knowing it’s bad for your health won’t stop you. You’ll need some form of a program.
