> Amphetamine and Modafinil have also caused these types of behavior in myself but none moreso than Methylphenidate. Why is this the case? I too have been legally prescribed such substances for medical reasons, and I have some of the same issues. The medications do help alleviate some symptoms, but during the initial ramp-up (like shortly after ingestion) I have worse symptoms for about an hour or so. Some of which occasionally include compulsive behaviors.
