In the case of long-term coffee intake, large doses of caffeine is a drug that can cause "caffeine poisoning". Symptoms of caffeine poisoning include addiction and a range of physical and psychological reactions, such as nervousness, irritability, anxiety, tremors, muscle convulsions (hyperreflexia), insomnia and palpitations. Most people take caffeine because of its stimulating effect, and many students take caffeine pills when preparing for exams and those on night shifts. Under the strict definition of addiction, only a gradual increase in dosage is addictive, and caffeine dependence is more appropriate. But under a widely accepted definition, all chronic behaviors that are difficult to get rid of are called addiction, so it can also be described as caffeine addiction. In addition, because caffeine can increase stomach acid, sustained high doses can lead to peptic ulcers, erosive esophagitis and gastroesophageal reflux disease. However, because both normal coffee and decaffeinated coffee stimulate the gastric mucosa and increase gastric acid secretion, caffeine may not be the only ingredient in coffee. Four caffeine-induced mental disorders verified by the Diagnostic and Statistical Manual of Mental Disorders include caffeine overexcitation, caffeine anxiety, caffeine sleep disorders and other caffeine-related disorders.
