Forgot to ask about Breathing (m)

Ok so I don't mean to be a PITA. But I forgot to ask about breathing! I'm starting to find a 'rhythm' with freestyle- backstroke let's not even go there- I get so distracted by the water splashing into my nose that I lose concentration quickly. But with freestyle- is it normal to feel as though you need to be out of the water longer to catch a breath as you get tired? I am noticing I get very haphazard in and out of the water (when I go take a breath and blow massive bubbles in the water) with my breathing when exhaustion sets in and I am just wondering if this is something experience will take care of in the long run.Thanks again! You guys rock :)
