The other downside to this Ramadan experiment is that it messes with exercise if you can't hydrate for half the day. (I'll go for a super-early morning walk all the same, and see if that helps.)

I'm also trying to figure out if my mood's so low from the fast itself, or from caffeine withdrawal. But when I'm water-fasting, coffee always drops away after a couple of days, so I don't *think* it's withdrawal symptoms.

No hunger, but low mood is 100% a symptom to watch. Will stop if it keeps up! 👌
