Due to my new job, I have to drive at least one hour each day after I finished working at night and I'm getting really tired while driving back home... I'm afraid I'll get hurt or cause an accident in the long term..

Is there anyone in the same situation?  
How could you overcome this?

There is a solution which I could buy?  

I have seen that newer cars can have a sort of driver monitoring system, does anyone have experience with these technologies?
