Waking up after a few hours and struggling to fall back asleep is called sleep maintenance insomnia. Before starting any medication, it is important to consult a doctor to identify potential causes like stress, lifestyle factors, or sleep apnea. For short-term relief, over-the-counter options like low-dose melatonin may be suggested. For ongoing issues, prescription medications that help maintain sleep, such as low-dose doxepin or suvorexant, might be considered. However, the safest and most effective long-term treatment is Cognitive Behavioral Therapy for Insomnia (CBT-I) combined with good sleep hygiene, like keeping your bedroom dark, cool, and screen-free. Please discuss these options safely with your healthcare provider.
