Hi, I had the same problem as you, all my shots just went to the right midway, but my Instuctor advised me to move my right right foot slightly back ( being right handed ) when addressing the ball . When you start your downstroke , try to brush your elbow slightly against your waist on the way down and follow thru. Hopefully this prevent a 'out to in' swing path. It works for me most of the time.
