      If you have hallucinations or any other abnormal thinking or behavior talk with your healthcare provider.

Examples of this are unusual urges to gamble, increased sexual urges, strong urges to spend money, binge eating, and the inability to control these urges. If you notice or your family notices that you are developing any unusual behaviors, talk to your healthcare provider.
