As already mentioned, I became braver towards the end of our vacation regarding my diet, as it was just hardly possible to eat healthily.
In the end, during our return flight, I ate everything that was served to me, even the dessert: A cake!
We flew overnight, again via Zurich. At home, I even ate the delicious Swiss bread in the evening. A few hours later, the bill came:
I woke up in the middle of the night with a very severe headache and only a Naratriptan tablet could help.
Fortunately, we are now back in Germany and it is no longer a problem to bake Farinata 😉 Also, fruits and vegetables are easier to get at reasonable prices here.
