KD, the outbursts could get better OR worse with the higher dosage. Some kids find the stimulant ADHD meds ramp them up. Our kid on Vyvanse was a guy on the edge-- think 3-4 cups of coffee, revved to breaking point. He had many more outbursts than usual, to the point where we had to discontinue it-- the focus wasn't worth the emotional volatility to us at this point. YMMV.
We found the nonstimulant Strattera worked well for attention without giving us extra outbursts.
Personally, I also wouldn't use just a pediatrician to prescribe these drugs-- I'm more comfortable with a specialist who sees hundreds of kids with the same diagnosis mine has, and has lots of experience with each med. Again YMMV.
