1 Answer

Answer :

caffeine causes headaches because of the physical withdraw your body is going through. Caffeine is a stimulant and with that being said if you are a heavy taker of caffeine either thru coffee, tea or in my case soda (mountain dew) when you stop taking it you will go through physical withdraw. Headaches, shakes, not being able to rest but not feeling energy are all withdraw symptoms. If the headaches get to the point of being constant and reg. Medicine isn’t working go to the doctor they can give you a heavy dosage or a adrenaline shot to ease it till your body doesn’t crave the caffeine anymore
