I've been on HRT for 10 years, now aged 63. Got dose down to VERY low, only using it Mon, Wed, Fri and all has been fine for the last 4/5 years, no symptoms at all............suddenly about 3 months ago back came the night sweats and the occasional day flush........so what's all that about??? Really don't want to increase the HRT as felt comfortable with the low dose I was taking, but the night sweats are really getting me down...........does it never end???
