Around a day and a half without any source of food, limited water and building my own shelter in the middle of nowhere. Would not recommend on the thirst and hunger side, but it was quite peaceful. I ended up eating a little bit of my flavoured chapstick, I was quite hungry and thirsty. Thankfully weather was mild so no heat or cold related issues shelter wise. I’ve been camping in tents when it’s gotten so cold that frost formed inside the tent, that’s not fun either. Once I made it back to civilisation, I had a long shower, drank lots of water, and ate two full plates of food. Almost threw up afterwards from overeating.
