Been very tired and much worse, for 2 days now Have posted before, even my voice feels flat, find it hard to talk and just feel low. I feel as though I'm moving underwater and having probs focussing in my good eye, have cataract in other. Just v v tired and vary from day to day in spite of Levo being the same. The same pattern as before I took it. Are these variations normal? I struggle now with orchestra Very worried that something like MS is there as well.Blood tests show hypothyroidism.
