Nervous, anxious, easily frustrated/pissed off, jittery, glass-eyed, sleep-deprived and with slightly irritated bowels. That's at least what I got from drinking coffee six days per week and nothing I want to resume ever again. Coffee is a neurotoxin, stimulant and drug whose addictive and harmful effects are never discussed in the mainstream. Probably because political leaders, big-pharma and big tech-companies see it as much easier to manipulate and control people if they are attached to drugs of various kinds. At least, it makes their job a whole lot easier if people are sick, addicted to caffeine (and/or other substances) and can't think for themselves, hence questioning their purposes.
