I've experienced eye twitching from a number of psych meds. At least, I assume it's the meds; the twitching could be just a thing the body does sometimes. Also, it could definitely be related to anxiety. I've never thought of it as a TD symptom; I don't think it is.
I've found that gently resting my finger on the spot when it twitches can help. For me that twitching (which is really annoying) can go on for days at a time, then it all of a sudden stops.
