If you miss a dose of quetiapine and have trouble sleeping, it is not recommended to stop abruptly but rather to gradually decrease the dosage. It is important to consult with a pharmacist to create a personalized tapering schedule and receive close monitoring. In addition to medication, implementing good sleep hygiene practices such as turning off screens before bed, maintaining a consistent wake-up time, and avoiding stimulating activities in bed can also help improve sleep. Avoiding naps during the day, limiting caffeine intake, and practicing relaxation techniques can further aid in promoting a healthy sleep routine. It may take some time and patience to establish these strategies, but they can be beneficial in the long run.
