Hurray, to compare and contrast, I am updating that I no longer am experimenting with Ritalin or Adderall due to drug shortages. My neurologist prescribed me a generic version of Nuvigil called armodafinil. It is a wakefulness agent that in theory, should deter extreme fatigue. It is not an amphetamine like adderall. I will keep you posted but so far, mixed results. Helps keep me alert but still symptoms linger for 1 to 2 days.
