Very Easy Feeling Tire Now

Don't know why, recently I feel that I am very easily getting tire and always want to sleep. Maybe is because I wake up too early? Usually I'll back to bedroom and put my two daughters to sleep around 9.30pm, and I will fall in sleep just after them. It is sleeping early right? But I did wake up early too, sometimes 5am sometimes 6am. But not sure why still feel tire all the time, maybe I need some Energy Pills to help me boost my energy. Or just resign from my current jobs and being stay at home mother. :p
