Do a google search for "wristless riskless" and read the David Leadbetter article from golf digest. I started using this technique a couple of years ago and it improved my game a lot. Worst mistake I see in people with the same problem as you is they decelerate into the ball. They often take way too much backswing and slow down into the ball. Practice taking a much shorter backswing so you have to accelerate into the ball.
