We feel that there is enough data to support a caffeine-withdrawal syndrome. There are enough people who go into withdrawal — that if they don’t get caffeine, it becomes a real syndrome and can affect work, sleep, or whatever they need to do. So we’re suggesting that it ‘make the big leagues’ and become part of the DSM to make sure everyone is aware of it.
If you enjoy your morning, and afternoon, and evening, coffee. Keep it up. There are enough crazy people in the world already.
See "Caffeine Withdrawal Is Now a Mental Disorder" for more on the report.
