Coconut water fast 21 days

Hello :)

So I'm embarking on a coconut Water Fast and would like some words of wisdom or advice from anyone who's done an extended one before.

I've got Water Fasts and juice fasts up to 7 days but this time I'm aiming between 21-25 days :)

sadly I can't go to a fancy retreat or anything but I am in good health with no medical problems.

Has anyone done this length of a coconut Water Fast unsupervised before?

Thanks :)
