When I quit smoking, many years ago, I needed a lot of help. One piece that stuck with me was to remind myself, during urges, "what do you really want?" I wanted to be a non-smoker.
That might sound glib to many, but I found it helpful. Sounds like you outlined your goals, "what you really want."
If you find yourself wanting a snack, perhaps you can fill the void with a tall glass of water.
If you are able, keep moving. Perhaps get a pair of walking shoes and take walks.
Good luck!
