I have a family member taking it for anxiety and probable ADHD (in denial on that). Tried SSRIs and SNRIs for anxiety and weight gain and lethargy were big problems. While Wellbutrin can increase anxiety, it was worth a try with little other options. It improves the anxiety a little, but only tired when not taken consistently (mood all over the place when not taken daily as well). Eats a lot less when taken consistently too.
I can’t speak to ADHD symptoms, but I have seen people who it works well for.
Here’s some info and user reviews on Wellbutrin/Bupropion:
