Oh, don't I know it. :) It took me about 6 months of living here to lose my native accent (Yooper). Now when I talk, my accent is mostly neutral... though I can do a pretty good West Texas drawl when I put my mind to it. "Y'all" is now a part of my everyday language, and I learned right quick to say "soda" instead of "pop"! Takes about 10 minutes talking on the phone with one of my relatives for my "native" accent to reappear... but as soon as I hang up it's gone again. :)
