You will know the dose is right for you when your thoughts stop wandering, you are actually able to accomplish something you set your mind to and you are able to organize your home and work area. You will also be able to hold a full conversation with interest and without interrupting whoever is speaking at the time, lol. You will know definitely when you have the right dose, the difference is night and day. At least this is how I know my adhd meds are working. Everyone is different though.
