No longer taking carbidopa/levodopa. The Rytary is time-released carbidopa/levodopa. With the Rytary 3 X per day (4 capsules) my has just responded to the need for down time dopamine. But I am still getting the anxiety and nervousness. Will seek ouit a new med to replace venlafaxene, if there is some med I could take where there were no major negative results. Will be speaking with my psychiatrist in search of something to replace venlafaxene. (Does anyone know of a useful anti-anxiety drug or mood stabilizer that would help reduce the anxiety and nervousness that might be created by a PD drug – like Rytary – which is suppposed to reduce off-time PD symptoms, w/o adding to them?
