Can you fall asleep on your back?

Answer 1

Yes, it just depends on how your body likes to sleep. Sometimes people can only fall asleep if they lay on their stomachs. Others its their sides, or backs, it depends on how you like to sleep and what's more comfortable to you.

To clarify a little better, yes. You can fall asleep on your back. In fact, this is the recommended position to sleep in because it keeps your back in it's natural alignment.
