Anyone else find it difficult to go back to eating over-processed, sugary, packaged, fast food etc, once you get used to eating clean?

I don't even understand the concept of cheat meals. It's not just a matter of indulging in sweeter tastes as you eat them, but I also now feel it in how my body feels after, like after a cheat meal of sugar and empty carbs, etc. I just feel like shit, like something is missing, feel empty or feel too heavy, cannot digest as easily etc.
