I'm in AK so I haven't hit a ball outside for about 4 months. Worked on my game inside though. Last week the practice areas thawed out and I hit them with a vengeance. Was striking the ball as good as I ever have, loving it. This week suddenly I have the shanks more or less. This happened to me last year about this time except that I started out with the shanks and recovered through some awesome lessons. I've tried the drills that got me back on track last year but they aren't working for some reason.

It really bothers me that I can go from feeling so grooved one week and then totall lose my swing the next week.

Any tips?
