Coffee can be addictive

Coffee drinkers can experience withdrawal symptoms if they don't get their regular dose in the morning. Researchers from the Johns Hopkins University in Baltimore found that one cup of coffee a day can produce caffeine addiction. Caffeine is the world's most commonly used stimulant, and it's cheap and readily available so people can maintain their use of caffeine quite easily. The recent study demonstrates that when people don't get their usual dose they can suffer from a range of withdrawal symptoms, including headache, fatigue and difficulty in concentrating. They may even feel like they have the flu with nausea and muscle pain. Investigators analysed 57 experimental studies and nine surveys to validate what a coffee drinker could have told them. Missing the daily cup can cause fatigue, grumpiness and severe headache. Experiments have shown that 50 per cent of people got headaches when denied coffee and 13 per cent were sick enough to lose time at work. It is possible to free oneself of caffeine addiction. People can be taught a systematic method of reducing caffeine consumption gradually over time by substituting decaffeinated or non-caffeinated products. Using such methods allows people to reduce or eliminate withdrawal symptoms.
