What position do you sleep in at night to get the best rest?

What position do you guys sleep in to get the best rest? Last night I was kind of tossing and turning and trying to find a comfortable position. I ended up taking a sleeping pill. Does sleep position matter? I’ve heard that it’s bad to sleep on your left side?

Do you use a pillow, body pillow, cover yourself in the sheets, etc?

I’d like to get better sleep and feel well rested in the morning. I’m thinking about buying a body pillow to help me sleep, or even try aromatherapy.

Thanks everyone!
