Does raising the head of your bed help with sleep?

I use thick pillows to elevate my head, when i'm flat i get extremely dizzy and nauseous.

It didn't really help for me

It helps me. When I’m too flat I feel like I’m slightly tilted upside down. It’s easier for me to transition to sanding with fewer symptoms as well.

I think it’s helping but it’s hard to tell!

I didn't notice it helped me
