If you fix the underlying cause of the anhedonia then you cure it. In my case its caused by low dopamine in the brain because the invega blocks it. So whats the fix? Well obviously anything dopamenergic will cure it temporarily but it has to have the least amount of damage. Meth will fry your brain but it is the most dopamenergic. Wellbutrin works on dopamine but it isnt very strong otherwise it would be addicting. Parnate is the only other anti depressant that works on dopamine which is why I want it so bad.
It's more like ap's block certain kinds of dopamine receptors in various brain regions, not so simple as just less dopamine. Meth certainly fries brains, and fast. Wellbutrin is basically only dopaminergic in label, but mostly works on norepinephrine, which may help negative symptoms itself. They also have nardil, which isn't offered in my country. What's stopping you from getting parnate?
I have to say again that employment and going to school sped up my recovery so much that I didn't even really have much of a recovery period.
