My gluten sensitivity got so out of hand that I began twitching. Randomly a muscle in my body would twitch every few minutes 24/7. I saw a neurologist because I was convicned I was coming down with a degenerative neurological disorder. They said it was benign and stress related. It wasn't until a while later when the symptoms got worse and I had incredible anxiety all the time that I found out it was because of a food sensitivity. Been gluten free for a while now. Twitch free too! Early on when I was learning the ropes of a gluten free diet I had a few accidental exposures. I twitched almost more intensely than I remembered before. I'd say its common.
