Yes you break the fast every sunset and stop eating at every dawn. You do **not** remain hungry\thirsty for 72 hours consecutively. An uninterrupted fast during day and night is called وصال and is generally makruh on the ummah.

>### نهى رسول الله صلى الله عليه وسلم عن الوصال

> Allah's Messenger (ﷺ) forbade Al-Wisal
