If the problem is the position of your neck, the answer is the only thing that can hold that position all night. The right pillow.
Most pillows make it worse, not better. They go flat and drop your head too low, or they are too tall and bend your neck up. Both pull your spine out of line. Research on pillow height shows the wrong height changes the load on your neck. So the ordinary pillow in your cupboard may be part of the reason you wake up tired.
The Aeyla Dual Pillow was built for this exact job. It holds your head, neck and spine in a straight, neutral line all night.
