Familiar. I did similarly, when I had a four hours part time job (with work contract) in Hungary a few years ago. I had to wake up early to arrive at the workplace in time (at 08:00 in the morning).

Similarly to you, I often drank two or three cups of coffee, sometimes even four cups of coffee in the morning.

Currently I also work, but currently I do not have a work contract. I can start and stop working anytime I would like (I am doing small jobs every day since 2024.07.28).
