Ask Daniel #27: To Joseph, Matt, Ed, Audrey, Vector333 and Jade

Why does Joseph have dark circles under his eyes? Matt is starting to work nights as a nurse and will need all the sleep he can get. He has started bedtime restriction but is not getting predictable results. Ed is very worried that CBTi will not work for him. Audrey wonders if I really believe hormones never have anything to do with how you sleep? Vector333 sleeps has 3-4 nights of little sleep cycled between longer periods of sleeping better. Jade is having night sweats and has not slept well for 3 weeks, could this be sporadic fatal insomnia?

Do you have trouble sleeping? Can’t sleep? Have questions about insomnia or sleep? Please leave a comment or send me an email at and I will be happy to share my thoughts as a video or audio reply.
