Welcome to the world of hormones. Mine do the same. Talk to your doctor about it. I have cyclic night sweats and anxiety that makes me feel like my heart is beating oddly around my period. So, talk to your doctor. There are some supplements you can take and I sleep with a fan at the end of my bed. Of course, you'd then want to rule out anything else that could be going too when at the doctor. But it sounds like hormonal sensitivity. good luck
