Heading towards reaching the 72 hour mark!

A few weeks ago I completed my first fast which was around 39h. Despite some headaches and less strength, there was nothing particularly discomforting during that period of time. I am currently in the middle of my 72h fast (rn at 51h) and Im feeling weirdly normal? On day one I had a light headache that luckily didnt kept me from falling asleep, this morning I woke up feeling as if nothing ever happened. No hunger, no weakness, no headache, no nothing. Only in the afternoon, I had the hunger kick in but it went away after a couple hours and some salt water (other than that I dont use supplements). I am surprised by how easy it is for me. I hope tomorrow will be the same (on the other hand I dont want to break my fast when I feel completely fine).
