For me Oakmont can be incredibly frustrating, tapping a putt and seeing it roll 30 odd feet past the hole, the par 4's with almost no hope of getting there in 2 but that's part of the beauty of it too. You really have to think your way round the course, get to know the greens so you avoid the downhill putts, lay up on the long par 4's and play a wedge close.
Don't expect to end up with a St. Andrews score, try for par and occasionally you'll be rewarded with a birdie. Finally being able to get the big R9 driver and G10 irons has helped tame it for me too.
I can understand why you'd want to give up on it but try not to, it can be a really rewarding course when you get it right.
