"i have been taking wellbutrin 300 mg xl for over 10 years after a major depression.  it was very effective at stabilizing my mood.   it also helps with my mental concentration and focus.  i tried the generic which didn&#039;t seem to work as well. i am under extreme stress with a challenging job and s difficult relationship (separated now) because of my partners alcohol abuse.  i was very fearful of another episode but so far have managed to remain stable.  i would be lost without it."
