There are a lot of ways to get your caffeine in the morning, and how much you crave can be determined by your genes, according to a new study.
Researchers from Harvard University, University of North Carolina and Brigham Women's Hospital teamed up to find the source of caffeine addiction.
The study says your genes may determine, in part, how much caffeine you crave.
They narrowed it down to two gene variations that could lead people to drink more coffee.
The study says these genes determine how much coffee someone drinks and how the caffeine in it metabolizes.
The full study is out in this month's issue of PLoS Genetics .
