Hi all, I have finally been prescribed thyroxin . Whoopie ! It's been a slog but my last bloods showed a marked increase which I presume indicated hypothyroidism . It's a small dose but hopefully it will help . So looking forward to getting my health and life back on track . I have been so tired and alongside a multitude of other symptoms it has stopped me in my tracks . How long do you think it will take before I notice any change ?
