HOT FLUSHES VANISHING - HRT for 6 weeks and the hot flushes are almost at zero

been using HRT for 6 weeks and waking in the night at what feels like 200degrees has been significantly reduced to only waking slightly hot for a minute, daily hot flushes are down to a slight raise in temperature when getting slightly stressed, I cant believe I put up with daily hot flushes before and could not go back!
