Hey Lisa,
With the usual night sweats I always got days 2,3,4, you are OK and all of a sudden you are having a hot flash and are drenched and feel like you're in a sauna. You kick off the covers and then 10 min later, you are cold and put the covers back on. Then this process repeats itself all night. I always get those the first 3 days or so.
The other day though, (day 9, I think) the chills and night sweats started again. With these sweats I'm getting now.
