巧克力，是它让你夜不能寐？
[b]Chocolate - Is it Keeping You Up At Night?[/b]A lifetime of[b] insomnia(n.[/b][b]失眠) [/b]issues has made me [b]compulsively(adv.[/b][b]强制地，禁不住地)[/b] careful about my habits. In the interest of getting a good night's sleep, I try to exercise daily, resolve stressful issues before bedtime and keep my bedroom free of distractions. Oh, and I never, ever have caffeine after 3 pm. A diet coke, a cup of tea -- if it's got even a trace of caffeine in it, it's not going into my mouth at night.
Sadly, I might have to cut out chocolate before bed too. According to The New York Times, a bar of [b]dark chocolate[/b][b]（黑巧克力）[/b]can have the same amount of caffeine as a cup of instant tea -- about 30 [b]milligrams[/b]（n.毫克）. That's not all -- dark chocolate also has [b]theobromine[/b][b]（n.[/b][b]可可碱）[/b], a known [b]stimulant[/b][b]（刺激物，兴奋剂）[/b]that has been linked to sleeplessness.
The [b]silver lining[/b][b]（一线希望）[/b]? This is only true of dark chocolate. White chocolate, on the other hand, has no caffeine or theobromine, but it does have a lot of sugar.
长久以来的失眠使我不得不关注自己的生活习惯。为了睡个好觉，我试着每天坚持锻炼，缓解压力，排除卧室的干扰。对了，我还从来不在下午3点后摄入咖啡因。为了避免哪怕一点点咖啡因，我也绝对不会在晚上饮用健怡可乐或茶。
然而，我可能还得在上床前把巧克力也戒掉。按照纽约时报的说法，一块黑巧克力中含有等同于一杯速泡茶的咖啡因,大约30毫克。还没完呢，黑巧克力中还含有可可碱，一种导致无法入眠的刺激物。
还有一线希望？这只是对于黑巧克力而言。至于白巧克力，它们却不含有咖啡因和可可碱，但却含有大量的糖分。
