Well, I did it. I managed to thrash about in a controlled manner for 20 minutes and not drown or kick anyone.

I did succeed in breaking my 10-year-old googles in the first 10 seconds, so I didn't put my face in very much (contact lenses). I think I did ok with breathing- both sides no less!- when I did put my face in. It took awhile to coordinate the whole exhaling and inhaling thing.

I think that my new goggles and I will go again Thursday

Thanks for all the tips and support, ladies! Feel free to keep 'em coming!
