Many things can make me tired ( or does it occur to me not to be tired ? Mmm ? ) but I wonder whether it's a direct consequence of drinking much coffee or not.

First, I regularly have difficulties for falling asleep even when I'm very tired ...
11pm Thinking, switching the light on ... writing my thoughts down (yes, I know ...), switching the light off ..., writing SMS ... Oh my god, already 1am !!!

After the night, I am usually sleepy the whole day at work, ..

Caffeine binds on receptors for the neurotransmitter "adenosine"₁ which makes one sleep.
Secondly and because the adenosine receptors multiply, I get more sensible to it when there's no caffeine intake.
In other words, I drink coffee, I feel am stimulated during few hours then I feel over-tired.

Caffeine also increases the adrenaline₂ production through increased dopamine₃ secretion.
What wouldn't be freed in normal circumstances is released which means the very little energy left is consumed and one finishes more tired than before having drunk coffee.

Moreover, I often have headache ... And, I keep private the consequences on XXX !

I know: I'm naturally anxious and I spend my time front of a computer, so ... it also can explain much of it

What about you ? Do you feel addicted to coffee and how your body seems to behave ?

You may already know about the fear of failure but have you ever heard of the fear of success ?

According to Freud₁ and Laforgue₂, failure would be a kind of preventive self-castration and success may symbolize realization of the forbidden Oedipal desires.

What is your point of view ?
