The Mayo Clinic warns that people who drink more than four cups of coffee a day may feel a range of side effects, including insomnia, nervousness, restlessness, irritability, stomach upset, fast heartbeat and muscle tremors. How sensitive you are to caffeine depends on a number of factors.
Amounts of caffeine up to 250 milligrams show very few ill effects and may help individuals feel more alert. Doses exceeding 1,000 milligrams may affect sleep and cognitive performance. Side effects of quitting caffeine appear roughly 12 to 24 hours after cessation of coffee consumption and may include headaches, irritability and constipation.
