Before you try the pump maybe you should look into Rytary. I assume it's in Canada maybe a different name. My wife takes it because the Stelevo she was taking contained comptan and made her hallucinations/delusions worse.
Rytary is Sinemet but in timed release form and usually given every three hours. My wife took all the other PD stuff but no longer does, don't know if they did much good anyway. Sinemet is the only pill that works.
