It's not possible to restrict submissions to one per user. Forms do not require users to be logged in so there is no way of definitively knowing if someone is submitting a form twice. There are some ways you can process your submission data to remove duplicates.

First export your submission data to a spreadsheet application. Then you can filter your submission data by IP address or a unique field (such as email) to remove duplicate submissions.
