Has your doctor tried this? I've been stable long enough where my doctor is willing to try stimulants. Negative symptoms (avolition, apathy, anhedonia, fatigue, etc.) haven't improved even though I feel like I've fully recovered from psychosis. My doctor just put me on a low dose of Concerta. It seems to be helping with anhedonia. I'm able to enjoy music for the first time in a very long time. Hasn't done much for motivation so far.
