I see you found my message :-) Glad you are feeling better today.
I'm not sure if you are now on water only, ( and no supplements: please do give yourself the gift at some point of trusting the water only process. . . )
but if and when you do undertake a water-only fast, you will see that it is an up-and-down thing. Every 'down' will pass. Always do your best to break a water only fast on an upswing. One written work I often recommend is Edward Purinton's fasting manual. You can google that. The "Soil and Health Library" has a lot of rare and out-of-print books. I like Purinton's sense of humour, and his writing style.
You can probably search though my messages too, and see if anything catches your eye. I've posted a lot on CZ, over the years, when I felt I had something to share.
