Lone Writer writes "The editorial section of the American Journal of Psychiatry for March offers the opinion that Internet addiction is a 'compulsive-impulsive' disorder, and should be added to the official guidebook of disorders. The editorial characterizes net addiction as including 'excessive gaming, [online] sexual pre-occupations and e-mail/text messaging'. From the article: 'Like other addicts, users experience cravings, urges, withdrawal and tolerance, requiring more and better equipment and software, or more and more hours online, according to Dr. Jerald Block, a psychiatrist at the Oregon Health and Science University in Portland. Dr. Block says people can lose all track of time or neglect "basic drives," like eating or sleeping. Relapse rates are high, he writes, and some people may need psychoactive medications or hospitalization."
