Bupropion
"I was suffering from constant fatigue, possibly depression-related, in addition to my ADHD when I initially sought treatment. Bupropion really helped me get out of the worst of it, lifting my mood and increasing concentration. Unfortunately, over time it also increased my tics (comorbid Tourette's) and I developed really annoying urinary problems, while the positive effects seemed to wear off, so I discontinued usage."
