The symptoms of caffeine overdose might include restlessness, nervousness, excitement, flushed face, insomnia, cardiac arrhythmia (or irregular heartbeat), muscle twitching, irritability, gastrointestinal problems, and a rambling flow of thought and speech.

This may lead to some withdrawal symptoms, such as headaches. Teas, energy drinks, colas and chocolate contain caffeine, though in smaller doses. People who consume those products regularly may have withdrawal symptoms when they try to stop.
