"Fatigue is a term used to describe an overall feeling of tiredness or lack of energy. It isn't the same as simply feeling drowsy or sleepy. When you're fatigued, you have no motivation and no energy."

"Sedation, or sleepiness, is a common side effect of many antipsychotics. It is more common with certain antipsychotics than others, such as chlorpromazine and olanzapine. Sedation can happen during the day as well as at night. So if you experience this you might find it very hard to get up in the morning."
