I’m struggling with the same thing now.
Like I’m literally 48 hours into a 72, and I’m 16 hours dry.
I have a headache. It sucks and I’m also looking for tips.
My hunger isn’t bad at all fasting… but my thirst is insane as is my dependency on caffein :(
Same, this is the reason I haven’t done more dry fasting. I don’t drink a ton of coffee but that cup or two gets me going for work. One idea I’m going to try soon is to get in coffee in the morning with water/electrolytes then dry fast until the next day and have coffee late. At least then you get your coffee and a 24 hour dry fast in to start. Obviously you will still have to go without coffee eventually if you increase your fasting hours.
Good luck!
