They're crap, aren't they? I wonder if night sweats might be one of the many things that everybody experiences differently?
For me, I was waking up several times a night with a feeling of absolute panic, like I had to get away from something. I mostly felt as though my body was waking me up to have the sweat, as once I was awake, or half-awake, I'd then be drenched head-to-legs, if that makes sense. Sometimes there'd be dreams interrupted, sometimes not.
Then when I cooled down, I was struggling to get back to sleep because the bed was soaked and smelled stale and gross - my sense of smell seems to be a bit hyper these days. And then I'd be freezing. This was happening a few times a night.
HRT patches seem to have stopped the night sweats - touch wood!
