I agree with the other posters.
Switching up your diet in different ways (cutting out animal products or caffeine, eating more fruits and veggies, drinking more water, eating lighter meals) and making different lifestyle choices (exercise more often and not before bed, take a nap in the afternoon) might help you sleep less.
But it also could be that you sleep so much simply because that's how you're biologically wired. Some people need a lot more sleep than others.
