How much time a cup of nescafe ( a coffee ) on the morning still be effective ( in hours ) ?
A doctor has provided 1 answer
Coffee: Depends on your drinking habits. People who drink a lot will become used to its effects. Scientifically, it will usually take the body around 5-6 hours to clear half of the caffeine- this may also depend on the status of your liver, smoking habbits and whether you are taking other medication.
