I had approx 22 drinks over 18 hours and stopped drinking 6 hours ago: when is it safe to drive?

I’m a 26 year old woman, 62kgs. I drank at a birthday party from 10:00am til about 4:00am. I left my car at the place where we drank and need to go pick it up this afternoon so I can get to work tomorrow. But I’m paranoid that if I get pulled over I’ll be over the limit.
