Response to--->Caffeine

I agree with you that caffeine affects differnetly at differnt time and different people. Most people say that they dare not drink coffee at night or even in the afternoon for they won't be able to sleep. But for me, I like coffee and I often have coffee in the afternoon and at night especially on weekend for I'd like to see the Korean series that I can see only at weekend (or sometime I read the book at night). After drinking coffee I feel sleepy and I have to stop Korean series or books at all, then go to sleep. So I don't think that caffeine in coffee affect to me.
