mg 3 years ago. At the same time they put me on HRT which I came off myself as was worried about taking it. Seems from reading up about hypothyroidism it closely mimics ' The change' I still suffer mood swings, dry skin, thinning hair, insomnia etc. I had awful night sweats which ceased about a year ago but now they are back with avengence, is this normal? Had bloods done in January and was told all was ok.
