Since we're talking about cross addictions.. I think I'm actually addicted to a person. I can't even call it a relationship because it's not (although it is very sexual). But since I quit smoking I think I started unintentionally being more clingy which has essentially pushed him away, and now there's a lot of distance but not enough to cut the chord entirely. I think the only thing to do at this point is to stop initiating contact (ever) and let the chips fall where they may. This should be easy and simple and common sense, but for me it's just not right now.
I've dabbled with occasional sugar binges but smoking and this d@mn guy have been the hardest ones to beat for me since I quit drinking. So I totally understand it doesn't matter how trivial or illogical it might seem to someone who doesn't share that particular inclination.
