S.M.
Hormones? I had my first hot flashes postpartum. They were awful and always at night while sleeping. I don't know why at night. I dont' have them anymore, but I notice that I can be freezing at night (2 layers, 3 blankets, and socks) but wake at 2am sweating. Must be something about the body at rest. I imagine this is what happens at menopause too, heaven help us all.
