Golf advice: Severe outside-in swing

[otctrader]

Okay, golf season is around the corner in the Northeast and I want to actually make a bona fide effort to improve my game this year.

I've been playing for over 10 years but am plagued with a severe outside in/over the top swing. My divots are literally at a 45 degree angle pointing left of the target, no exaggeration.

Anyone have this same problem or know how to combat it? I can hit 1000 range balls and consciously try to fight it but it doesn't work.
