I had a mild case a few years ago, here's a few things I did that got rid of it. Got rid of my hair trigger release aid, quit shooting at targets for awhile and just shot judos at grass clumps, stumps, whatever. Also bought a back tension release that didn't allow me to anticipate the shot and shot it for a few weeks. Finally, bought an index finger release for hunting that I could adjust to a heavier trigger and hooked the trigger deeper into my finger and use back tension to release it.
I just picture the target in its underwear. Seems to help me..... Someone once told me to just grab the bow and shoot into something like a haybale at night when you cant see from like 10 feet. Just focus on anchoring settling in and releasing. I have never had it luckfully.
I was told by an Olympic archer (female by the way) to go to a target 5 yards away and aim dead center then close your eyes. Concentrate on your back tension, breathe deep and slow and release your arrow while your eyes are still shut. Do this repeatedly and concentrate on your release, not the bullseye. You'll get back on track quickly. Good luck!
