Is really easy for me to get addicted to coffee  or caffeine, I drink three or four  cup of coffee per day. the first is when I get out to the bed, the second one is after lunch and the third is after diner. I don't know the coffee control my central nervous,but I present with a variety symptom like a intense headache of my life and suddenly I decide to drink one cup of coffee, other is when I drink coffee very late at night and then I can'

t sleep for long hours, also sometime the coffee give me abdominal spasm but in conclusion with coffee I lost stress and tension , i feel relax and give me  energy. is difficult to me go a day without coffee.
