When I clicked on this thread, I was kind of hoping this was where it would lead! Hooray for you for acquiring this new skill.
As a former competitive and then long-distance for pleasure swimmer, I'd like to add another skill suggestion or two. Some teachers have you breathe to one side, first for one full stroke, then every other full stroke, always to the same side. When I was finally coached to breathe on alternate sides, it made a world of difference in relaxed, distance swimming for me. Since you haven't had time to develop any deep-set habits, I'd suggest learning this trick before you develop a preference. I hope I've explained this clearly. Think left-right-left(breathe to right)-right-left-right(breathe to left). And gently reach on every stroke. Stretching your body through the stroke feels great and helps you slice through the water with ease. Very calming, plus you look great too.
And guitarstv, you made me laugh. I have a terrible fear of dark water, which is why I prefer swimming pools and stay as far away from the drain as possible ;-)
