Newly diagnosed w/ADHD & husband also has ADD

I'm newly diagnosed as an adult with ADHD. Seven years ago I was diagnosed with Bipolar 2 (what was called Major Depressive Disorder). The symptoms for these 2 conditions are very similar and overlap. Since having been diagnosed, I have started to wonder if I was MISdiagnosed . My husband also thinks I may have been misdiagnosed because the more I tell him about ADHD symptoms the more everything makes sense! His symptoms are different than mine. He's more neurotypical. 

I just started treatment with Wellbutrin, even though it is not approved by the FDA to treat ADHD. We've noticed I'm a bit sharper, I can remember things and my mind isn't so foggy. The only problem I'm having now is sleep. I will give time for the Wellbutrin to work (can take up to 8 weeks) and if I don't feel much of a change by October I may request a stimulant instead. Had anyone been on both? What do you notice is the difference? Thx
