How can I add a newline to a field's displayed name?

I would like to add a newline to some of my single line text field's displays (or titles), but have had terrible results with trying to find a solution.

I would like to do something like the following:

Original formatting:
How much time do you expect to spend on E-bukatsu.com per week? (text field here)

Formatting I'd like to achieve:
How much time do you expect
to spend on E-bukatsu.com per week? (text field here)

I'd really like to be able to do this, because currently my embedded form is too wide for the page and requires horizontal scrolling.

Would someone please advise me in this?

Thanks in advance.
