二、Sip All Your Coffee by 10 A.M.

　　早上10點前將你的咖啡喝光

　　Get your caffeine fix right when you roll out of bed. It'll take effect within half an hour and stay in your body throughout the afternoon, when people who wake up early are typically most exhausted. You can have all you want, but just make sure you switch to decaf or some other noncaffeinated drink by 10. That way, it'll all be out of your system by bedtime.

　　早上一起床就喝下咖啡的話，它會在半小時內生效，并在你體內一直持續整個下午，而這時正是那些早起的人們最容易疲勞的時候。接下來你可以想喝啥喝啥，但是要記住，一定在10點左右換成脫咖啡因咖啡或者其他沒有咖啡因的飲品。這樣咖啡因的作用在你晚上睡覺前就會消失了。
