Anxiety Without a Reason

Redness of the Face

If your friends or colleagues say that your face turned red, but there is no reason for shyness or feeling awkward, this may also happen because of too much caffeine.

Fast Heartbeat

If you feel like you have just finished jogging, but you are still sitting at your office desk, caffeine may be the reason.

Extent of the Overdose

If the overdose is not that severe, and you just experience the specified effects in a light form, this is not such a big problem and will pass in a while. However, it is recommended not to take products containing caffeine the next 48 hours. But, if the symptoms are getting hard, it is a must to consult a doctor.
