"i&#039;ve been on wellbutrin xl 150mg for 7 weeks now (adult add and comorbid depression). i experienced some of the common side effects such as dry mouth and loss of appetite, but everything came back to normal after a few weeks. sadly, i haven&#039;t noticed much change in terms of mood or attention/focus... it hasn&#039;t worsened but it hasn&#039;t improved either. then again i know this is a low dose. i saw my doctor today and he switched my prescription to wellbutrin xl 300mg. i&#039;m starting tomorrow and i hope it will work better for me. i&#039;m eager to give it another try since i&#039;ve seen a lot of positive reviews on here :)"
