Why I am I suffering from jet lag?

Yeah, it's going to be there for a while. Maybe not that long though just a few days and you'll be better. Your body's just trying to adjust itself to the enviroment. With light and all. Whatever time your body was used to anyway whether it be 2 hours or 1 will still adjust itself and you will still have jet lag. It's alright though it's normal. Hope you feel better! :D
