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. Sonata generally does not cause next-day sleeepiness but a few people have reported this.
Alcohol can increase the side effects of Sonata or any other sleep medicine.
Do not take any other medicines without asking your doctor first. This includes medicines you can buy without a prescription. Some medicines can cause drowsiness and are best avoided while taking Sonata. Always take the exact dose of Sonata prescribed by your doctor. Never change your dose without talking to your doctor first.
