Oh my gosh! I'm sorry I missed this one when it was posted. I get eye twitches whenever I start some protocol that is good for me. There have been several supplements that caused eye twitching when I started, i.e. Ubiquinol, magnesium, mk-4, and iodine. I've been on low carb for five years now. The times when I have returned to real healthy, low carb either after a full blown binge or simply after eating a lot of low carb fake food (like every summer), I get the eye twitch. I wish I knew exactly what caused it, but I tell myself that the eye twitch means my body is healing.

ETA: The opposite of my eye twitch occurs when I eat something bad for me - it's a mild headache on my left side, right next to my eye. I can't remember which eye twitches when I've begun something good (maybe I'm detoxing?), but I think it's my right eye.
