Since there are so few documented examples of Modalert 200 mg addiction, some people have questioned the drug's potential for addiction.
However, since modafinil affects neurotransmitters like dopamine, it has been proposed that because of the drug's mood-altering properties, addiction may be possible.
A few accounts have also surfaced of users reporting symptoms of withdrawal, including difficulty concentrating, drowsiness, low energy, sadness, anxiety, and dyspnea. But they are uncommon and usually extremely modest.
