been on HRT for 3 weeks. 2 squirts of everol in the morning,, 1 ustrogen at bedtime. For 3 weeeks I have had the best sleep I have had in years & I felt amazing. But for the last 3 nights, my body has been back to its old tricks and I have been awake for the day at 3.30 am - hence posting at this stupid hour.what can i do?
