What is a common side effect of bupropion used for smoking cessation?

Bupropion, when used for smoking cessation, is associated with several common side effects, one of which is insomnia.

By enhancing these neurotransmitters, bupropion can lead to increased wakefulness and energy, which may manifest as difficulty sleeping.

Insomnia is noteworthy among its side effects because it can significantly impact a patient's quality of life and adherence to the smoking cessation plan.
