Cons:

1. Potential side effects: Like any medication, modafinil can have side effects. Common side effects may include headache, nausea, nervousness, anxiety, and insomnia. Less common but more severe side effects may include chest pain, rapid heartbeat, skin rash, and psychiatric symptoms such as mood changes, aggression, and depression.
2. Prescription required: Modafinil is a prescription medication, and a healthcare provider’s prescription is required to obtain it. It should only be used under the supervision of a qualified healthcare professional who can determine the appropriate dosage and monitor for potential side effects.
