I was on Wellbutrin for ADHD, and found it helped me be less depressed (it is an anti-depressant that helps also with ADHD). Then my PNP prescribed stimulants also for the ADHD (not Ritalin, but Vyvanse). She cut down the Wellbutrin when she did that and said I may be able to completely stop the Wellbutrin because she said stimulants are very effective against depression. I do find they help me be "up." If they are helping you, then stick with them. I think often stimulants are not prescribed as a firstline treatment for depression because they are on a more restrictive prescribing schedule (for drugs of abuse/addiction) than ADs. You can't get automatic refills on your prescription, can't have your scrip phoned in to the pharmacy, must see your provider in person for a refill, etc.
