Saw your post and had to add my two cents. A recent study on golfers with the yips found that most were afflicted during their putting game (not your case) and had 25 years on the course (not sure how long you've been at it). That said, it does happen on other shots and the more technical the shot, the more likely the yips will rear their ugly head. It is also far more prevalent during course play than on the range.There is a belief that it is a neurological condition (focal dystonia) and others believe that it is a psych state issue.
How do you cure it? Try all of the above solutions; they all seem as if they might have a positive effect. I would add that you should concentrate on your breathing during the shot. Make sure that you have exhaled during your shot, as muscles relax during the exhalation process and tighten when you inhale. This has helped a number of the golfers that I've dealt with clear up the issue. Relaxation visualizations and self-hypnosis are the next step and will clear up most psych based problems. Medical experts are studying beta-blocker therapy for severe cases.
If I can add more to your understanding, let me know. Just keep swinging and it'll work out. Good Luck!
