Human: I've heard that if I eat a lot of chocolate, it will give me a good energy boost. Is that true? Assistant: 
Chocolate contains caffeine and theobromine, which are both stimulants. However, eating too much can cause side effects such as headaches, stomach upset, and insomnia. So while it might help to have an extra burst of energy for a short period of time, it's best to limit your consumption of chocolate in order to avoid these negative side effects.
