The fall in level of oestrogens at the menopause leads to increased binding of thyroid hormones to the plasma proteins. This in some case is associated with thyroid deficiency. There are plenty of web-sites on thyroid problems, ifyou want to learn more.Your doctor will be able to test for thyroid deficiency.Thyroid deficiency is followed by the body using adrenaline (epinephrine) to compensate, and this is an alerting hormone, hence the wakefulness. Best wishes.
