Diet is very important for helping to keep our pain levels down, in particular inflammation which can increase pain levels.
We all have 3 main tastes that need to be satisfied, salt, sugar and fat, it's just what our brains tell us we need. I try my best to follow an anti-inflammatory diet and I have eliminated all processed foods. More and more I find that my old cravings for sugars, salt and fat have diminished quite substantially. I understand about the need for coffee but it is a major stimulant to our nervous system and it can really flare me up. I gave it up a few years ago now.
Here is a good article about anti-inflammatory foods.

While I'm not pain free I am feeling the difference since I changed my diet and would have to say that I am still managing fairly well. At the very least I'm much healthier for it in the long run.
Wishing you all well.
