I would try something non-habit forming like valerian root or melatonin first before going to prescription drugs.

Also, at bedtime try to keep the TV and/or reading to something that's not too interesting or too boring(shopping channels/business TV helps me).

The main thing is to distract yourself away from thinking about sleep while trying to fall asleep. A hot shower or a peaceful walk may also help.

Try to maintain proper sleep hygiene.
