I assume you can go back to regular C/L temporarily with your doctor's help. here's the inactive ingredients in rytary
"The inactive ingredients are microcrystalline cellulose, mannitol, tartaric acid, ethyl cellulose, hypromellose, sodium starch glycolate, sodium lauryl sulfate, povidone, talc, methacrylic acid copolymers, triethyl citrate, croscarmellose sodium, and magnesium stearate. The capsule shells all contain gelatin and titanium dioxide. All blue capsule components contain FD&C Blue #2 and Yellow iron oxide. All yellow capsule components contain yellow iron oxide. All capsules with black imprinting contain iron oxide black. All capsules with blue imprinting contain FD&C Blue #2."
it would take some work to see if there are posts stating side affects from any of these ingredients causing your spaciness.
