If your principal sleep difficulty is awakening prematurely after falling asleep, there is no evidence that Sonata will be helpful to you. There are many different sleep medicines available to help people sleep better. Sleep problems are usually temporary, requiring treatment for only a short time, usually 1 or 2 days up to 1 or 2 weeks. Some people have chronic sleep problems that may require more prolonged use of sleep medicine. However, you should not use these medicines for long periods without talking with your doctor about the risks and benefits of prolonged use.
All medicines have side effects.
These side effects with Sonata occur most often within an hour after taking it, so it is especially important to take it only when you are about to go to bed or are already in bed. Sleep medicines can make you sleepy during the day. How drowsy you feel depends upon how your body reacts to the medicine, which sleep medicine you are taking, and how large a dose your doctor has prescribed. Daytime drowsiness is best avoided by taking the lowest dose possible that will still help you sleep at night. Your doctor will work with you to find the dose of Sonata that is best for you.
