To avoid coffee addiction, a person needs to limit caffeine intake. If you feel like you need a few cups of coffee per day, you might want to give up drinking coca-cola and other products that may contain caffeine. If you do not exceed 3 cups of coffee per day, then there's no need to talk about serious coffee dependence. If you drink more than 3 cups of coffee per day, especially strong drip coffee, you may get a strong psychological addiction, which will eventually lead to feeling unwell without drinking at least one cup of coffee. Only moderate consumption of coffee is completely safe.
