I'm no expert...but have looked into this whole sleep dis function thingee because of friends and family members who suffer from it. I went to a few classes and here is the jist of what they were endorsing.
1. taking more than an hour to fall asleep on too many occassions is not normal unless you are ill or experiences a heavy stress load. If this lasts, you should seek medical help.
2. "shutting down" in the middle of the day is a sign of extreme exhaustion and you need to pace yourself so that this does not happen too often. It can be damaging and affect your immune and nervous system.
3. waking up several times during the night is equally damaging and you need to again find out the cause and treat it.
There are several things you can do to balance your sleep and awake time so that you can operate at peak level and sleep restfully for at least 6-8 hrs. each night.
I won't bore y'all here, but trust me their are several solutions to all of this. Each person suffers for a different reason. You need to find your "source of sleeplessness".
These courses helped my friend and people I care about very much.
A good night's sleep is worth it's weight in gold!
Sweet Dreams!
