Does anybody have same problem ?

I am taking Addrall XR 15 Mg for my ADD, but when effect is tapering off afternoon i start feeling irritated, cant stop thinking about same thing over and over. I take Xanax 05 to control my anxiety. Doc prescribed Celexa for this problem but it totally work opposite way to ADD. It alliviates my ADD symptoms and reduces Addrall effect.
