I find myself so much colder when fasting. I am in a hot bath while I type this out. Have you tried electrolytes for the headache? Also, a few aspirin is better than breaking the fast. However, I only have 4 5 day fasts under my belt. I like to give in around 3 as I’m not so much hungry as I am bored and deserious. Don’t feel ashamed id you give in you did 3 already and can always try again after a refeed.
KCKO! Fellow traveler
I’m currently 67 hours in to a 600 hour fast. You’ve got this. Make sure you’re getting your electrolytes! Not sure why but I’m finding this easy so far where I normally find it exceptionally difficult. I’ve started supplementing my electrolytes from day one though and it’s made things significantly easier!
