It is the caffeine in coffee that keeps people awake - also, if you add sugar, that will contribute to helping to keep one awake!. It is the same for colas - the caffeine in colas such as Coke and Pepsi, will also keep most people awake!.


Caffeine interrupts our daily sleeping patterns by altering the chemical reactions in our brain!.

After drinking a hot cup of caffeinated coffee, the caffeine causes three different chemical reactions that boost our energy levels:

It energizes us by pumping the hormone adrenaline into our systems!.
It increases dopamine levels within our bodies!. Dopamine is a neurotransmitter that stimulates our "pleasure areas" in our brain making us feel good!.
It blocks the connection of adenosine to nerve cells!. Adenosine is the chemical that attaches to receptors in the brain and causes drowsiness by slowing down nerve cells activity!.Www@FoodAQ@Com

Because of the amount of caffeine, mostly around 100-300 mg of caffeine!. You can get the same buzz from a highly caffeinated energy drink or probably a caffeine pill ( 300 mg per pill)Www@FoodAQ@Com
