I can totally relate.....and it's a really awful that you wake up in the night covered in sweat. My thoughts are perimenopause, or a medication, or a combination of meds. Even some supplements can cause hot

flashes/night sweats. My physician gave me a very low dose of a blood pressure medication and it was fantastic. I now have substantially fewer night sweats and hot flashes and they are less intense. Not sure if I'm allowed to post the name but it's clonidine and this is considered an 'off label' use.
