Sometimes stimulants can have the opposite effect. Think of giving a kid a Coke -it has caffeine but it calms them down-usually in ADHD. I don't know if that helps but drugs effect people differently. Ive tried Addrerall for attention and noticed it did help depression but had to stop taking due to Headache and high blood pressure. I've also tried Nuvigl and thought it was the best thing ever but just started feeling like I was racing all the time.
