i second the notion. i had the exact same problem as you my friend except i had trained myself to keep my finger back and just jump it around and slap the trigger. this bad habit is a tuff one to break. i recommend the blind shooting as well it really helps. another thing i do, is i keep my finger on the side of my release but in front of my trigger so that when im ready i dont have to jump the trigger my finger is already close, but w/out the temptation of being on it and jumping the gun.
now what has helped me the most honestly. this is somewhat strange but i promise you it will work. i promise. shoot w/out your sight on. look through your peep adn focus on form. stare at the bullseye adn breath, fell youself relax, and when you feel completely relaxed, gently squeeze the trigger. when you shoot its supposed to be a suprise that anything even happened, and if you do this technique right thats what it will feel like. stand 5or6 yards away and do it for days. you will be broken and your mind will be disciplined. im telling you this out of complete experience btw. its not like its hunting season anyway and you can usually just slap your sight back on and it should be fine. good luck though as it is a tough habit to break.
