After one year on Requip alone, I added Sinemet. I experienced sleep attacks the first year on Requip. By the end of year two, I was at 30 mg of Requip and have stayed at 30 mg for the past 5 years without sleep attacks. I might attribute some agitation to Requip but agitation could come from other sources. I'm very sensitive to food blocking the benefits of Sinemet to the point that eating a good diet and getting adequate nutrition is probably my biggest battle. Requip appears to not be affected by eating. I take 150 mg Stalevo 8 times daily or every three hours. That's a lot of L dopa. Where I run into trouble is if I need to add more Sinemet due to eating. Then I risk dyskinesia: the pits of PD. I feel lucky in being able to tolerate Requip at 30 mg as I think it potentiates L dopa predictably where as increasing L dopa gives very unpredictable results.
