That's a rough situation.

I'd try doing poultry, fish, oysters, and butter. And pork's good if you don't follow those religious traditions. Some places might even have goat and lamb, those are also good, but sometimes a bit too lean for my taste. Same with wild animals.

While beef is always best, other meats are OK in its absence, then eggs, cheeses, milk. All of these are much better than other supermarket foods, and absolutely superior to salbutamol and salmeterol, as well as cannabis - and I believe limiting your meals to whatever animal sourced foods you can get will likely resolve your symptoms.

And you're correct, I'm from Croatia. We have solid beef here. We even have grass fed, but I'd have to travel to Zagreb to get it. The butcher there says there's plenty demand, but very few producers. I imagine they're being taxed into oblivion at the behest of the EU overlords and unelected bodies that would have us eat crickets instead.
