Yup, exactly this. I quit smoking multiple times and dieted one time (lost ~20 pounds).
You have to "hack" your brain into enjoying the unpleasant sensation like it is something good. Even if you feel like the world will end, nothing happens.
Doing other activities help indeed, but in order to do this, you sometimes need massive changes in your daily habits/lifestyle. I feel like these changes are the hard to maintain part since you are constantly fighting to do "the right thing" instead of "the pleasurable thing"
