Yes! I have survived fasting while on my period. I was Water Fasting those days also but I broke that with miso broth. You don't want to eat anything right now. Your body is busy with your period. Sleep if you can or take a warm bath. Can you get away from chaos and put on some Ray Lynch or calming music? I feel for you. I felt very very low energy on my period while fasting. If you just can't go on without something have some veggie broth, miso broth (for salt cravings) or some cold sweet juice (no sugar) and go back to water when you feel better. No matter what YOU have to listen to YOUR body.

Love,
Kate
