I must admit that I am addicted to coffee, but not coffee in general, just coffee in the morning. During the rest of the day I no longer feel like it or feel like I need it. But if I don't have that morning coffee in the morning, wow, I have a bad day. I get a headache and I feel very sleepy all day.
I also don't like any coffee, I only like it with milk. I really enjoy it a lot and it wakes me up completely to get through the day with energy.
