answer:It varies. Usually I make it through the night, but sometimes I go on jags where I wake around 3:00 and stay up a couple of hours Nd them return to sleep. I sleep fewer hours now than when I was younger. Also, once my thyroid went haywire my sleep did too. I don’t regulate very week, so depending on whether I’m over-medicated, under-medicated or properly medicated affects my sleep. Still, overall I sleep less than when I was younger, which to me means I’m on the downhill towards death. Oy.
