My Adderall is making me throw up, please help?

So, I recently started taking Adderall in the morning because i was diagnosed with ADD. It has helped my schoolwork a lot, but the only problem is that I usually like to wake up at 6 in the morning and go running...but when I'm on Adderall it always make me nauseus, and half the time I throw up. I take Adderall around seven; so right after I go running; but for some reason, the Adderall from the previous day is still affecting me or something and always makes me puke :( Running is really important to me because it helps me focus almost as much as the Adderall. I thought it would go away but it's been three months, and it's still happening. I'm really getting tired of throwing up, and I've lost 20 pounds (I went from 135 to 115; so I'm not dangerously underweight or anything now, but I wasn't trying to lose weight....) Is there anything I can do to make myself feel less nauseous? Or do I have to stop doing one of these activities? Any help would be much appreciated :)
