Waiting 30 minutes
Not unless you want to. There's no reason you need to wait, though.
Please note: I AM NOT A DOCTOR. If you want medical advice, talk to your doctor. Whatever I post, there is probably some surgeon or other health care provider somewhere that disagrees with me. If you want to know what your surgeon thinks, then ask him or her. Check out my blog.

You don't drown by falling in the water. You drown by staying there.
