I regret drinking a cup of coffee last night before going to bed.It made me cant fall asleep until 3 o'clock am.I feel struggling，I feel the pain exist in every corner of my body.
I am lessoned by the lack of common sense.I am a complete idiot.
Suffering from headache，I decide that I will never drink coffee at night.I am still too young too naive.
So I learned a lot from this event.Good sleep for me is as important as good meal.That is my conclusion.
Noon has come I wish I will have a good sleep that allow me to energetic enough to work till late night.
