Lady GaGa has revealed that she finds it difficult to sleep at night, because she is forever plotting her career and kept awake with an overactive mind.

The overworked singer admits that she can't stop thinking of her next move. "My passion is so strong I can't sleep," GaGa explained during a conversation with OK!. "I haven't slept for three days... I lie in bed and try to pray and breathe. "I have a very overactive mind. I'm the sort of person who'd never take medication to calm myself. It's maddening. But I love what comes out," GaGa said to the magazine. "If my destiny is to lose my mind because of fame, then that's my destiny. But my passion still means more than anything. For some people, fame kills it and becomes more important than the music or the performance. But for me fame is like rocket fuel. The more my fans like what I'm doing, the more I want to give back to them."
