Take it out of the bag!!

I find that people pull out the driver way to much...in fact, with my game alot of the time playing it will put the "trouble" into play.  I have a nice hybrid I use that takes most of those out of play....besides, I only have a 8 iron in vs. a wedge, so I don't think it's worth it.  However, alot of the time you have to use it, and as you can tell by the best pga tour pros, if you hit it well, you score well.

So for you, here is my recommendation.  I haven't seen your swing, but from what your saying, it has to be a swing flaw.  I reccomend getting a video lesson from your local PGA professional.  Do some research and find out the best teachers/prices in your area.  I've taught for over 9 years and find that changing one or two swing flaws brings out the straight and confident hitter in almost every level of golfer for every club in the bag.  This is true especially with the driver because the length of the club and length of the hit will expose even the minute flaws in the swing.

Get a video (visual) lesson, and watch your driver hit the fairway.

I recommend Zen Golf to all of my players.  The audio version is perfect for the exercises. 

For now, put in a 64 and take out the driver!  :)

Another Great book for the Mental side is The Golfer's Mind by Dr. Bob Rotella!!!!!  I highly recommend this one, my buddy medaled in the PAT after failing twice.  It has brought a whole new mentalness to my game.

I agree anything by Rotella is rock solid for the mental aspect of the game.

after the first round i kinda do the same thing. Try to hit shots i know i shouldn't and take clubs i know i shouldn't hit. What i do is just pretend it is the first round and before every shot i think "is this the right thing to do?" sometimes i even leave myself a note note to do stupid things haha. good luck!!

Make a plan for each hole.

Par 3's are a good guide. Look at the yardages of the par 3's for the tees you are playing, then plan the par 4's based on those yardages. There will usually be a couple par 4's that require a driver to reach those yardages, so you can use driver, or use a longer club on the second shot, or play short of the green and let your short game into play.

This will not only help your score on par 4's, it will help on the par 3's, because you are hitting the par 3 yardage all the way around the course.

Par 5's don't require a driver, even if I play the back I don't need a driver to reach the green in 3.

Most of the time the problem with driver is feeling you have to kill it, you don't.

Maybe you should take out the driver and use a 13* wood instead 

I believe the mental game starts before I show up for the tourney not at the tee.  Typically I will  work on my TEMPO the week before the tourney, you will find me hitting mostly wedges, chips, pitches &  3/4 speed shots, focusing on feeling smooth & solid.  I also spend alot of time putting thats also tempo based practice. Hitting solid - controlled iron shots & putting well gives me the confidence to score without having to hit bombs off the tee or try to overpower the course. During warm up & before they call my name on the 1st Tee I tell myself  that 18 pars will be tough to beat, then I remind myself constantly during the round. Typically as a rule on holes less than 400 yds I know that i don't need driver to make par and i weigh out my options before i commit to a shot. I typically look for the best angle to play in from. On the rounds where i am not flushing it, I am able to tell myself on the tee "somewhere around the fairway - somewhere around the green - then up & down for par" this helps me take off any pressure that i may be feeling for not having my A game and gets me back to smooth & solid swings.  Spending the week working on my tempo & short game has always paid off  with my thinking on the course during tourneys. It doesn't do any good to hit a 300 yard drive if your not hitting the wedge inside 10'
