Well, eventually I get moved past certain addictions. I'm not sure if this is personal failure on my part or what exactly.
In my experience there's always something I can do to combat a personal habit that is destructive. It may be small, but I believe the Lord honors that small thing and carries us the rest of the way (depending on the issue).
One of the biggest defeats can come from just looking at how giant something is and sort of giving up or trying to tackle it head on and just straight up failing. I think he will meet you there as well tackling it head on, it's imperative to recognize that without his help you can't do it. It may not be for this particular thing but it's always a good idea to lean on the Lord. So when you do overcome, praise follows.
Even in things I've done on my own, it's slower, less efficient, and I lose something vital (I'm pretty sure) in the process of doing it my way. Scars aren't fun
So...think of some way possibly that you can alter the habit. That's a good first step. Think about "how" this occurs. Do you feel a craving and cave in right away? Or is there something of a buildup?
I think all addiction should be handled delicately but sometimes there is room for experimentation.
Have you tried eating first? I mean just eating potatoes (which I'm pretty sure carbs break down into sugar) could go a long way.
I personally loved Kool-aid with sugar. There's this drink mix with sucralose that is Kool-aid now in a little squeeze bottle that is quite tasty at first but now I'm indifferent to it. Mostly because I want sugar and sucralose has ceased to really taste good unless I want Kool-aid. But I just ignore it.
Mixing up habits sometimes can go quite far.
I put a certain amount of sugar in my coffee and when I have it black and skip sugar I start to crave some type of sugar product at some point throughout the day. I usually ignore it, but the next day I do not skip the sugar, but if it's too sweet I don't drink it either. I think because possibly the body does have a need for sugar and that it will regulate it. The biggest thing is to treat it something like medicine and not overindulge.
Some meds can cause cravings. Zyprexa certainly does. Also pay attention to if the foods you eat are also high in sugar. Diabetes is a thing and if you are prediabetic sugar can exacerbate it. Sometimes additional knowledge on a subject can lead to more accountability with things.
