I'm doing a long IF today - plan to break it after 22 hours and I'm about 20 hours into the fast. I've been having a headache, progressively increasing in intensity, which I'm assuming is because of the fast. Any idea how to get rid of it? I'm drinking water to make sure I'm not dehydrated. I'm not hungry.
This is my first 22 hour fast. The longest I've done before is a 20-hour fast once.
