Night guards

Hello. I would like to know if most night guards are for the upper or lower teeth. I spent a fortune on a mouth guard that I'm supposed to wear at night and it goes on my bottom teeth. In the morning, I wake up with my jaw feeling stiffer than it ever does and I can barley open my mouth at all for the first few hoursof the day . Do you think that the mouth guard I have should go on my upper teeth instead of my lower teeth? Is it normal to wake up with such stiffness in the morning?
Thank you very much.
