Video would certainly help, but a few things to check....

A lot of golfers, thanks to all the quick tips and magazines, forget the real goal of the swing - impact.

The single best drill you can do at home with a mirror is to practice impact fix over, and over and over.

The flying wedges - is the left arm and shaft in line (face one), is the right forearm and shaft in line (down the line)? Did you take your grip at impact fix? Is the right wrist 'level'?

Is your weight primarily on the left leg at impact?

Get into impact fix, then practice small motions back and through from there. Your head won't move.

Slowly make bigger motions - when does your head start to move?

Odds are it is a flexibility issue, and letting the right hip move 'back' will actually help - and so will letting the left foot come up, roll up, from the inside edge, until you get the back of the left shoulder behind the ball at the top.

Imagine you want to hit the ball with the back of the left shoulder. Let you body move freely to get there.
