I was a big potato eater but when I stopped eating them (except when they were in moderation in some veggie dish), I didn’t miss them for 5 years… And then it just wasn’t the same anymore. I still eat some here and there because I can’t always ignore 2 kg boiled one in the kitchen for 4 days… But it’s very rare and very little.
I didn’t miss pasta for even longer (and had great substitute, egg + some paleo flour, fried, crumbled) but now I do miss the macaroni shape. It’s fun. One can slurp up soup and sauce with it
But properly eggy macaroni doesn’t exist and I can’t make them either. And the shorter pipe isn’t the same. So, my eggs still win. I could just eat normal pasta if I sooo wanted (I tried that a few times) - but it’s NOT GOOD. It has flour flavor, ew. And not enough egg.
I expect great flavor from my pasta. If it’s not delicious all alone, it’s not good enough for me.
I am all for good substitutions, I had great success with some
And it was clear it’s impossible for others (anything with their own unique flavor).
Sometimes I only need something to work in the role, different is fine.
I never grieved items, I think, I am lucky. If I want something, I eat it BUT if it’s unhealthy, I already lost most of my interest and I can train the rest out of myself while eating good, healthy food that is just the tastiest 
If I miss something, that’s some specific texture. Like wafers. I can’t make them but what I can buy has bad ingredients so I just go and make some other crispy stuff… One can live without wafers, right?
Crispy, crunchy options should be enough.
Sorry for the offtopic…?
