i get a headache now if i go a day without drinking coffee.
i also go to bed thinking about how nice it would be to wake up the next day so i can drink more coffee.
it sounds like a lot of people here get a headache if they stop drinking coffee. i used to think that was bad until i heard someone tell me that she threw up for a week when she stopped drinking coffee due to the headaches she was getting from lack of caffine!
