Dexmethylphenidate
"I'm not impressed with this medication.  My daughter was having some issues with Vyvanse, so her doctor put her on this.   Unfortunately she's back to her old self, completely out of control, taking hours to do a 15 minute assignment, playing with her paper, staring off into space, not focusing, etc.  First thing tomorrow I'm calling her doctor and putting her back on Vyvance. Last thing I want is for her grades to slip, she's already struggling enough as it is to keep them up. The nail biting from Vyvanse is just a minor side effect that we can deal with for now, otherwise she'll fail 3rd grade entirely."
