I'm 39 and for the last year I have a few nights where I've woken up drenched in sweat for no discernible reason. Could this be the start of the menopause or I am just hot? 
I'm on the pill. Maybe a stupid question but how do you know you're menopausal if you take the pill as surely the hormones will prevent it/mask it? And, if that's the case, why doesn't everyone who is able to just take the pill forever to stop all the hassle?
