I suffer from major depression and currently im taking Wellbutrin 300mg xl, Wellbutrin is the best medicine that gets me out of bed and makes me feel motivated and energiezed. However, I am also taking Celexa but i do not feel it making happy like Zoloft alone once did. Should i consider stopping the Celexa and add Cymbalta. Also since i suffer from ADHD would this combination help enhance my concentration and focus due to my ADHD
