What are the symptoms of caffeine withdrawal?
Regular caffeine consumption reduces sensitivity to caffeine. When caffeine intake is reduced, the body becomes oversensitive to adenosine. In response to this oversensitiveness, blood pressure drops dramatically, causing an excess of blood in the head (though not necessarily on the brain), leading to a headache.
(Seriously) time to start cutting down on it liao...after today's episode of headaches (have not drunk much coke for like, 3-4 days?), and after drinking one can for lunch, somehow felt better already.
Too much coke...
