hi, imhv, it's a great idea, and I think, rather nicely exemplifies 'the future' of water fasting.
(perfect for weathering many of the storms of water fasting... my feeling is, the sooner a person can get to a place of seeing through all transient ups and downs and veils of perception, the better. Bach flower remedies are good stuff, in my experience. I also make my own essences. I mention this just so you can see that I have some experiential familiarity with the terrain.)
I would put it on the crown of my head, or on the wrists - i favour the crown- :-) where it acts perfectly, without introducing any 'food' type substance that would confuse the system.
I may have posted about this subject before. you could do a cz search. If not, it was only because in general, i think people do not understand or appreciate the way the Bach essences work.
(but then too, lots of folks get tired of me advocating EFT as a great
Water Fasting tool)
best, Chiron
