Hello!
Every time I do a fast longer than 24 hours, I get mild to massive headache.
Snakejuice, less drinking, more drinking or more or less electrolytes. I tried everything, but nothing works. I drink black coffee, so its not coffein withdrawel.
Any advice for me?
If you’re sure that you are supplementing enough electrolytes and it’s not caffeine then the next likely explanation is that you’re experiencing a fasting induced migraine. Fasting is a known migraine trigger. It’s not a trigger for everyone but it is for some.
