I hope it's okay to post this here.

Makes sense to me, in theory.

 

Ever since starting Clonidine, sometimes my urge to blink is a bit less, and I can "satisfy" it with a softer, regular-looking blink. Other times, that won't do, and it HAS to be the hard, scrunch-up-your-face-and-pull-down-your-eyebrows blink.
