二、Sip All Your Coffee by 10 A.M.

　　早上10点前将你的咖啡喝光

　　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话，它会在半小时内生效，并在你体内一直持续整个下午，而这时正是那些早起的人们最容易疲劳的时候。接下来你可以想喝啥喝啥，但是要记住，一定在10点左右换成脱咖啡因咖啡或者其他没有咖啡因的饮品。这样咖啡因的作用在你晚上睡觉前就会消失了。
