Drowsiness
Drowsiness is a significant side effect of melatonin. This condition may lead to additional symptoms like falling asleep at the wrong times and forgetfulness. Apart from taking melatonin, other significant conditions can cause drowsiness, including mental state, medical conditions, and other lifestyle factors.
Depression is a condition that can cause drowsiness. An individual may feel dizzy due to chronic pain or issues that affect metabolism or mental states like hyponatremia and hypothyroidism. Excessive drowsiness without a specific cause can be a significant sign of a sleeping disorder. Ensure that you consult the doctor to know the cause of drowsiness.
Doctors can treat drowsiness with medical care. The medical practitioners can always ask significant questions related to snoring, sleeping habits, and drowsy feeling.
Agitation
Melatonin causes agitation [4] as a side effect in various individuals and causes a feeling of aggravation and restlessness. However, with a frequent sense of agitation or when it’s due to supplements like melatonin, there’s a need to consult a doctor.
