Scottie...you know what causes the worst problem for most of us? It's our expectations and misconceptions about the process of peri and menopause.
We all need to realize that we are starting to CHANGE....it's the change of life, right? What is not clear to most of us just starting is that it's going to KEEP ON CHANGING (for many of us, things will continue to change for the rest of our life). I don't know of anyone who had only one thing change and then everything stayed the same after that....am I making any sense???? hahahaha!
What I'm trying to say is that our bodies are constantly changing and we have to expect that even though some of our symptoms may go away, with the constant fluctuation of our hormones and basic aging factors, symptoms may return or new ones take their place. I look at it as exchanging some of the problems from our youth for possible new problems in our (ahem) maturing bodies. Well, a cartoonist has to have a different take on things, right?
Anyway, to answer your question.....your hormonal balance has probably changed again, so the nightsweats are coming back. You might want to find more ways to make your nights more comfortable and cool (check out the Chillow post), have a small fan gently blowing on you all night, try primrose oil, drink Sleepytime tea...... just a few ideas that I've personally used.
And just keep laughing!!! of course!
