Okay, this is an odd visual symptom I've been having for awhile now.
I see "motion trails". In other words, if I put my hand in front of my face, then move it to the left or right, I see a faint trail or "visual echo" of the motion. It's kind of like on the first Star Trek movie when the Enterprise when in to warp, except that I don't get the cool colors that was on that effect.

It's happening mostly with my left eye.
Does anyone have a clue as to what I'm talking about or am I still strung out on Xanax? (Though this started before the Xanax/smoking bunnies incident.)
