"i have been taking 300mg for a few weeks now and i have to say this medication has definitely improved my quality of life. such a big change from when i was trying zoloft, celexa, lexapro, etc. wellbutrin xl helps control my gloominess, anxiety, and even my appetite. i am more motivated to do things during the day. the biggest side effect for me right now is that i am more snappy and aggressive when i get angry, hopefully that will subside."
