Everything is normal and your body is processing as it should.
A good rule of thumb is don't finish on a low.
It is imperative , especially with the symptoms you are having, to really drink
up ... get that PH to a high level. Citrus and cayenne really break things down.
Drinking plenty of water as well and proper flushing in the AM via SWF.
Up your cayenne and the cirulation will increase the blood flow and filtration process.
Get sun,vitamin D, too.
Fever/high temp is partly caused by friction-thick blood. Drink up and the blood will be diluted/thinned , as well as the toxins / mucus getting expelled faster and more efficiently.
