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?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.At least from my personal study then, it seems 2-4 cups daily is not enough to get any adverse effects.
