How long to wait after a second round/final interview to ask if you made it where you were only one of three people ?

It has been 1 week now since i had my second round/final interview.

I wrote an email to ask basically what the status of things were.

What else should I do.. just wait.. It is driving me crazy.

As it was just 1 in 3 people .. i just think it shouldn’t take long you know.

But then again I was the first person to go into the second round and I have no idea when the other 2 people went in after me.

What would you do ?
