To help you feel calm and improve sleep, several over-the-counter options can help. Melatonin is excellent for regulating your sleep cycle, while supplements like L-theanine, magnesium, and valerian root promote relaxation. For persistent insomnia, a doctor might prescribe medications such as zolpidem, eszopiclone, or low-dose trazodone, which helps with sleep and anxiety. Please consult a healthcare provider before starting any new supplement to ensure it is safe for you. Practicing good sleep hygiene, like keeping a consistent bedtime, is also highly beneficial.
