My son is ADHD and has been on adderall 10 mg 2 times a day, now changed to 20mg am and 10 mg in pm, has been on adderall for 3 years now. I noticed when my son was 1st put on the medicine his attitude improved. He seemed more positive about things that happen to him, more upbeat, took things in stide a lot better. We recently had experienced a decrease in the helpful affects of the medicine and just yesterday increased his medication to 20 mg in the am, and again noticed his attitute and outlook to be much more positive. His teacher said he seemed happier. Has anyone else had this experience with adderall? The positive outlook/attitude adjustment?
