How Your Brain Becomes Addicted to Caffeine
I was hoping that the article would also mention some approximate amounts you have to drink per day to start to get withdrawal effects. Are there no studies of this?<p>As one personal data point, I drink 2-4 cups daily and a few months ago I decided to suddenly stop just to see what happens. The results were very unexciting: I felt nothing. No headaches, no fogginess, no significant loss of alertness (although I did need more time to "warm up" in the morning from my groggy morning states). Otherwise I felt normal and after a week of unexciting I just went back to drinking coffee because it tastes good and works when you need it.<p>At least from my personal study then, it seems 2-4 cups daily is not enough to get any adverse effects.
