It sounds like mostly positive effects. However, the brain hopping and inability to sleep don't sound good. U may want to talk to your doc about that. I have found that ADHD medication actually helps with anxiety. Are you still building up the dosage? That could be why. Also, not all medications cause that sudden dip once they wear off. Some come in extended release capsules so they last longer and gradually wear off. You could talk to your doc about that if you are still having problems with that.
