I have the same problem as you. WEnt see drs so many
times still can't help. I have tried this method b4 it works, and
recently the cable programme also taught the same method. Sleep
with your head at the edge of the bed, place the part of your head
(the part which is slightly above your neck) at the edge of bed.
Stretch your arms apart and take a few deep breaths to relax. This
works for me most of the time. Reason why the cable programme
recommendqa this method is because more blood will be circulated to
the brain and when this happens it helps the brain not to think too
much and thus able to sleep.
