A recent study coauthored by American University psychology professor Laura Juliano indicates that more people are dependent on caffeine to the point that they suffer withdrawal symptoms and are unable to reduce caffeine consumption even if they have another condition that may be impacted by caffeine—such as a pregnancy, a heart condition, or a bleeding disorder.That is a glucose metabolism problem, not a caffeine addiction. Caffeine reduces insulin resistance, that's why people drink it.
These symptoms combined are a condition called "Caffeine Use Disorder."
Stop making up illnesses and doing bullshit research and try lowering those people's carbohydrate intake instead.
