i dunno why they call it "keto flu" because it more closely resembles how it feels to be withdrawing from codeine. cold, nervous, irritable, sleepless.
when i get a flu i'm lethargic, dopey, irritable, everything smells different, something in my throat, lungs or sinus is out of whack, burning, dry, or irritable, and i get sleepy.
keto flu i can't sleep at all properly.
