Chronic TeaEye Twitching, Eye Twitching Eye Twitching, Eye Twitching Stress -yes Lack of sleep -yes Fatigue -yes Well! For someone living in japan, I’m surprised you haven’t found out that it’s likel;y due to some liver issue, soemthing called liver wind. You are probably easily stressed, may have other liver symptoms such as nausea, dizziness, tinnitus, fatigue, bloating, constipation/ diarrea, headaches. All due to liver issues. I recommend milk thistle or better even a consultation with a naturopath or an acupuncturist. A lack of Magnesium and B vots can be a cause, but get to the bottom of it as eye twitching can have different causes. Speciafically diagnosed by chinese Medicine. Wishing you all good health.
