I take Adderall for adult ADHD without the hyperactivity. I was never medicated as a child, but I grew up and had depression anyway. I think, if you ask me... that it deals more with having ADHD than with the medication. Of course, I am no doctor.
My daughter is on Concerta, which is similiar but not matching, with Ritalin ( a tamed down version, if you will). i sure hope that that rumor about causing depression is wrong. IN my opinion, it makes more sense that she might experience depression later on down the road because of her difficulties in school.... making the grades. I deals more with self-esteem also. Being SURE of yourself, that leads to depression oftentimes.
I love my Adderall, and though I'm not taking it for fatigue, I CAN say that it DOES keep me a little more wound up than without it. But I find that tolerable, since I have so much to do daily. It helps me to focus and finish projects (more likely to, anyway). It's a life-saver!
Only YOU can decide whether or not you can live with potential long term side effects, if there are any. To me, it makes my quality of life easier and with more purpose, than without it. The benefits FAR outweigh any side effects. That's just MY opinion.

I CHOOSE to take it. It's your choice also.
I wish you love and laughter,
