Every little bit helps. In the past few days I've had some trouble with my eyes. I wear multi focal contacts. Thursday I got an infections in the left one and since then haven't been able to see as well out of either one but have still been grinding. Constantly need to add drops so I can see better. I think it's had a significant impact on my play and I'm going to stop playing for a few days til I find out what's wrong with my eyes.

Whether it's eyes, health, or alcohol, I think even the small stuff makes a difference.
