I tried Provigil once and it triggered a manic episode. Adderall is an amphetamine. I wouldn't rely on either of these drugs for fear that they would work for a while, possibly elevating you into a hypomanic or manic state in which you are able to resume your martial arts, only to crash eventually from the inevitable depression that follows. You're already taking four psychotropics; maybe you could consult with your pdoc about tweaking your antidepressants to help your fatigue. As Velouria pointed out, the Klonopin could be sapping your energy or motivation.
