I can't get to sleep at night. Why not?

I
don't fall asleep for 3 hours or so, and I've tried every trick I know. Can
someone help me?
Try some warm milk before you go to sleep. Pour a glass of milk and put it in
the microwave for about a minute. I know warm milk doesn't sound very nice, but
it does help.
Natural remedies include warm milk, melatonin, valerian, 5-HTP and others that
you can find in a web search for "natural sleep remedies".
Sounds like you may have insomnia...see a doctor.
