I have been prescribed ritalin as an augmentation for ssnri meds. It helps with the fatigue aspect and lack of drive and all the other things associated with dopamine. Having suffered with very severe depression for decades now it is as Flee said better than nothing - better than not having it. I drink several strong cups of coffee a day. I have given it up before and it makes no real difference to my depression. But I do seem to like caffeine and the energy kick I get from it.
