I have tried Unisom to help me sleep but I still lay awake for hours before I drift off into a light sleep. Any idea why it is not working?

Unisom is an antihistamine that has one name but is available in two different generic drugs; diphenhydramine or doxylamine. Check your package of Unisom and determine which type you are using. Since you are not getting the effect you want, try to find the other version and try that one (or a generic).

If still not effective, then it is time to make an appointment with your primary care physician.

Do not drive, operate machinery or perform activities requiring alertness soon after taking this medication. Antihistamines can have several drug interactions with some prescription products. Have your pharmacist check any over-the-counter drug purchased against your regular medication list.
