Curious what others drink to get them through a longer fast?

I’m 75% into a 5 day water fast and I broke my own self imposed rule and had a black coffee.

I know this doesn’t break the fast, but on all my previous fasts I have been a bit of a purist and only permitted myself to have still spring water.

But this has become a bit dull and it would be nice to make my drinks on fasting days a little more interesting.
