At 16 years of age, experiencing nightfall (nocturnal emission) about twice a month is generally considered normal during adolescence. However, since you feel it is affecting your ability to study and are considering medication, it is best to consult a doctor. A clinician can evaluate your overall health, check for any underlying causes if nightfall is unusually frequent or accompanied by other symptoms, and recommend appropriate steps or treatment after examination and any necessary tests. It is essential to avoid self-medicating with RB Tone Syrup or any other medicine without medical guidance, as the cause and need for treatment should be clinically determined.
