Hello and hope you are doing well.
Please don't venture to take sedatives and controlled substances without the supervision of a doctor. Besides, drug-drug interactions, we never know the metabolism status unless tests have been done to justify their prescription. Inability to sleep could be problems with initiating sleep or maintaining sleep is called insomnia. Problems with breathing (Obstructive sleep apnea), certain medications, restless leg movements and sleep walking/talking could contribute to insomnia. Follow good sleep hygiene measures like going to bed at the same time, waking up at the same time, avoidance of alcohol, smoking and caffeinated beverages. Please consult your primary care physician if problem persists.
Hope this helped and do keep us posted.
