"All of a sudden" changes in your swing?

[tuffluck]

I was playing good golf up until a month ago or so, for me anyway.  I was consistently hitting in the 80s and my handicap was down to just under 15.  Then "all of a sudden" I developed a slice in my driver.  It didn't go away and in fact got worse.  A few weeks later the irons followed.  I took some videos and immediately saw I was coming over the top, but my body literally would not allow me to swing differently.  I took a lesson hoping this would be the key, and it was a nightmare and did not help at all, and in fact maybe made the matter worse.

Since then I've been watching lessons online and slowly working the slice out, but now contact and distance seem to suffer.  I almost feel like I am only 2 months new to the sport again.  It's very weird, and it was almost an overnight transformation.  I shot in the 80s twice one week and the next week I could not break 110.  The last time I shot in the 100s before that was probably 3 months prior, so there was a definite "all of a sudden" factor here.

Anyway, I'm wondering if this kind of stuff happens from time to time to many golfers?  Or if my hand/eye coordination just decided to give up on me for no reason?  Needless to say it's frustrating.  I play a lot less golf now because a round in the 110s is a round I'd rather have not played.

Yes, it definitely happens to all of us.  I just go back to basics and work on set up and do drills at the range to maintain consistency.
