Yeah, unfortunately, Adderall
is one of those drugs
that have to be upped periodically until they cannot up it anymore. Talk to your doc, tell them you don't think the dose is strong enough, and they'll work with you. Adderall is NOT an antidepressant, and unless your doctor has told you directly to stop taking your antidepressant, DO NOT STOP TAKING IT! This is not good for you, your body, or your mental health!
So, in other words, talk to your doctor, get the dose upped.
