Yes, there are alternatives, and it is good that you are seeking them. Adequate sleep is incredibly important for your overall health and well-being, so finding an effective sleep aid is just as important.
Valerian: Valerian is an herbal remedy known for its sedating effects. There are multiple studies that indicate that it helps with insomnia, though its effectiveness for anxiety is still uncertain. As with any treatment, be sure to ask your doctor before taking valerian. It may be natural, but it can still have negative reactions with other medications.
Trazodone: Trazodone was actually approved by the FDA as an antidepressant, but it has since proved itself an effective sleep aid as well. Doctors are allowed to prescribe it for this purpose.
Lifestyle changes: If you are prone to eat big meals, drink alcohol, smoke, exercise, or watch TV before bedtime, consider replacing some of those activities with healthier ones. Having a small snack and a warm glass of Ovaltine, meditating, or stretching at night are much more conducive to a good night’s rest. Having a consistent bed time and wake-up time also help you sleep better. For more suggestions, see Sleeping – Dealing With Insomnia after Hysterectomy.
