Hope you have a good trip :) I know the struggle! I’m a vegetarian and often it’s very hard for me to find dishes I can eat in many countries. I have shifted towards renting Airbnbs with kitchen and making rice or pasta with local veggies for most of my meals for this reason.
I would suggest getting a book called Thinking Fast and Slow, and reading it slowly and deliberately, less than 5-10 pages a day. It not only tells you how to find these kind of fallacies but also why you’re likely to fall for them and how.
