I used to get that from stress. When my eye lid started to twitch people started to back off... But I haven't had one in years.
My advice have a salad with lots of differnt veggies (lettuce, cellery, carrots, cucumber, mushrooms, broccoli, coliflower, tomatoes, then toss som tofu, chicken or cheese on top. Add crutons and your favorite salad dressing to taste) that should replenish any nutrient your missing.
