At nikkas talking about smoke some kush. As a matter of fact, don't do any drugs to try and fix the problem because you may become dependent on them. I had a similar situation happen to me a few months ago. I was going to bed around 12 and waking up at 5 in the morning like

My homegirl gave me a Tylenol pm to take. Man that shyt had me in such a deep sleep that a nikka was drooling

I still woke up at 5, but I was able to go right back to sleep.
I said fukk that, I'm never taking one of them shyts again. It works too good. My same homegirl who gave me one has to take one before she goes to bed every night. She is basically dependent/addicted to them.
You may be suffering from some form of anxiety to be causing you to wake up early, or your sleep pattern/rhythm may be off.
I suggest going to bed a few hours later to get your circadian rhythm back in order.
