Our emotions could trigger our adrenaline to keep on running even when our bodies are already tired. I already experienced that, and it only stopped when what we had in our mind was done. Some people may say it was easy to resolve, but I could tell that it wasn't. Even if I try to divert my mind to thinking about other stuff, it still goes back there. It creates some stress, especially when you're winning big. That is why I believe this is the normal thing that happens to everyone.
