<human>: Hello /r/AskDocs! I was diagnosed with schizophrenia in 2014 February due to a series of delusion of reference and the severe anxiety caused by the delusion. Now I am totally certain that I am delusion-free and psychosis-free. And I have no hallucination from the beginning. But now the major problem changes to **chronic fatigue**.

I am currently studying math in a college. And I found that I really easily feel mentally fatigue when trying to pay full attention to the lectures. The length of each lecture is typically 2 hours. And almost in each lecture after I paying attention for about 1 hour I started feeling intense mentally fatigue so that I can't follow the  lecturer any more and have to take a sleep immediately after the lecture. Moreover, the severe fatigue usually developed into strange headaches. I know I am not so healthy now, since before being diagnosed with schizophrenia I can pay full attention to each lecture and do the homework / solve the exercises for hours immediately after each lecture.

My psychiatrist had let me tried several drugs but I still cannot figure out which drugs solve my chronic fatigue.(The obstacle is that I don't know **how to distinguish the "fatigue" is my symptom or is the side effect of drugs**.) Currently my everyday drug combinations are Abilify 10 mg  + Wellbutrin XL 150 mg + Rivotril 2-4 mg + Biperiden 2 mg. + Amitriptyline 10-25 mg.

BTW in 11/27 evening in Taiwan (UTC+8) my headache/ fatigue became so severe that I took Rivotril **30 mg** once. I feel under this high dose my headache is relieved much, and the side effects (dizziness, sleepyness) do exists but only slightly and are not oblivious enough  to notice.

Give me the gist of the text in a nutshell
<bot>: What is the most effective / most popular drug (in the U.S.) and its dosage that is used to relieve the symptoms of Chronic Fatigue Syndrome? I wish to discuss this fact with my psychiatrist .Thank you! :-)
