Mary is having insomnia. Which piece of advice would you give to help her deal with it?

A) Take sleeping pills.
B) Go to bed every night at different times to "shock your sleep system."
C) Study in bed and then go immediately to sleep.
D) Don't do anything but sleep in your bed.

The best choice would be to not do anything but sleep in your bed. This will help Mary associate her bed with sleep and make it easier for her to fall asleep when she goes to bed. Taking sleeping pills should only be done under a doctor's supervision and guidance. Going to bed at different times can disrupt her sleep schedule and cause more difficulty in falling asleep. Studying in bed can also associate the bed with a stressful activity instead of a relaxing one.
