One thing you could make is a change to your thinking. You say "I HAVE" to have something sweet after a meal. Did that include breakfast? If not, then it's just a thought, not a need.

Isn't it really that you are USED to thinking that a meal isn't finished until you have a sweet thing?

How about starting to say: I once thought a meal had to finish with a sweet but now, I just eat some extra protein.

It should not take much time before that self-defeating thought changes. Protein eaten when you crave sweets gets rid of the craving.
