Can you tell me if there are adhd medications that don't cause restlessness/insomnia?

Depends: If you have found that you get these symptoms from several different stimulants you may just not be able to tolerate them. The majority of patients with adhd who take them early enough in the day and at the proper dose do not have significant problems. There is a non stimulant called strattera (atomoxetine) that could be tried. Speak with provider to make sure you have correct dose and no drug drug interaction.
