Compare caffeinism and the possible Caffeine Use Disorder

What will be an ideal response?

Caffeinism is excessive use of caffeine. The symptoms of this can include nervousness, irritability, tremulousness, muscle twitching, insomnia, flushed appearance, and elevated temperature. Caffeine Use Disorder is not a recognized substance use disorder by the American Psychiatric Association's DSM-V. But there is evidence that some coffee drinkers meet the general criteria for a use disorder, including withdrawal: headaches, fatigue, decreased vigor, and increased depression scores. Some participants were unable to perform everyday tasks when deprived of caffeine.
