Howdy. Talk to you doctor ASAP. Go over every symptom. I'm in grad school too and I know what you are going through. I'm inattentive ADHD (big time). My wife is actually ADHD/Hyperactive and while getting her undergrad degree she discovered the university actually has a disability resource center and apparently most or all colleges do too. With a doctor's note explaining her conditions (since ADHD is a learning disablity and is protected by federal law) she then worked with the disability center and they assigned a note taker for her classes and she even made arrangements to take her exams in a private, quiet room, with extra alloted time, and unlimited breaks. It was a life saver for her.

Go back to your doctor and get some different meds. See your doctor since a PA cannot prescribe a CII medication although I maybe wrong since that is on a state by state basis. If Adderall (IR or XR?) wasn't good then try something else such as Ritalin or Focalin (improved cleaner form of Ritalin) or even Dexedrine (cleaner amphetamine than Adderall). Once you get a med that works with you then adjust the dosage that suits you best. Get a note and go to your school disability center. They will handle everything from there (any teachers, departments, dean have to accomidate anyone with a disability).

BTW, I was just diagnosed back in August and I'm 33. Good luck and keep us informed.
