Not enough sleep: It sounds like you're experiencing real symptoms from lack of sleep. Sleep is crucial to maintaining body functions, especially attention and memory, but also bodily functions like activity and energy level. I don't like to prescribe sleep meds, much better to try natural means so your brain can do what it's supposed to: rest and restore! Hope you get a break soon!
