larryst5,

Welcome to the forum.

Rytary has the same components as Sinemet, levodopa and cabidopa, but it is packaged differently.

So, I think the most likely cause of your nausea is the speed at which extra levodopa was introduced. You went from 1000mg per day of levodopa in the Sinemet to 2245mg levodopa per day in the Rotary.

See FDA prescribing information for details of how to introduce Rytary.
