Attention lapses due to sleep deprivation due to flushing fluid from brain

hmm.. this is interesting... the article says "spinal fluid exits the cerebrospinal fluid (csf) flows out of the brain... I wonder where it discharges these waste products. I ask because it is believed we have a sort of chimney on our backs. I think I read this on the article of the Irish lady who could detect alzheimers years before any modern medical detection systems. But maybe it is discharged in the gut? via the mesentery, the new organ they finally named fo rthe stuff that holds our intestines together. If anyone knows where it is discharged, please comment, I'm interested in this, because I do prolong waterfasts every 3 months, and I strongly believe the brain drains waste into my mouth during that time, because the taste in my mouth is godawful, but if there are other exit points the brain discharges waste, we probably need to know about them.

The description of the mesentery as a single organ dates to the time of Da Vinci, at the latest.

I believe it's discharged basically half directly into the venous system in the neck, the other half goes through the lymphatic/glymphatic system and ultimately also the venous system in the neck. That being said, that's just based on our very crude understandings and I'm sure there are other pathways.

Why do you think that the taste in your mouth is waste draining from your brain and not the result of some metabolic changes in your body from the fast? Ketosis is known to cause a metallic taste in the mouth, for example.

What I understood from youtube gurus, take it with a grain of salt, is that your brain is taking ketones as source of energy to preserve the little glucose that goes into the system, and as result it consumes less oxygen.

But I'm not sure the mouth taste comes from the brain's waste.

To some degree, if you had your brain inflamed by bad eating habits, fasting would revert that and make the flushing more efficient as well.

Again please take with with double grain of salt, since I don't even know inflame brain is a thing for sure, or the correct term.
