There are people who stay away from coffee when jetlagged: I don’t!
Coffee helps me to survive those hours where I would like to just lie down and sleep. And coffee helps me against the heat! How you might wonder? Well, black strong and on ice! Seriously cold coffee somehow makes me stay awake more than warm one.
Really nice is that the coffee doesn’t taste watered down, although there is ice and water in it (iced americano), the taste is still really strong. I wish I could find that at home as well!
And once it is empty, you just get a new one…, they told me to stay hydrated 😉
