The benefits and disadvantages of drinking coffee: overuse

In the case of long-term ingestion, high doses of caffeine are a drug that can cause "caffeine poisoning." Caffeine poisoning includes addiction and a range of physical and psychological side effects, such as nervousness, irritability, anxiety, tremors, muscle spasms (hyperreflexia), insomnia and palpitations. Under the strict definition of addiction, only gradually increasing doses are addictive, and caffeine dependence is more appropriately described, but under a widely accepted definition, all chronic, hard-to-break behaviors are called addictions, so caffeine addiction can also be described.) In addition, because caffeine increases acid levels, continued high doses can lead to peptic ulcers, erosive esophagitis, and gastroesophageal reflux disease. However, because both normal and decaffeinated coffee stimulate the stomach lining and increase acid secretion, caffeine may not be the only ingredient in coffee.
