Dear Trish, For the best effect, Sinemet CR should be taken 30-45 minutes before meals, just like regular Sinemet. If your Dad has nausea with Sinemet, he can take it with meals, but it will not be as effective, as the food will slow down its early absorption. If your Dad is experiencing on-off fluctuations, it would be best for him to take CR prior to meals.
