The short-acting medication — what you’re taking in the afternoon or evening — releases all the medication at once, giving kind of a rush of the medicine. The long-acting is slowly released over time. And not all time-release medications are smooth and even in the release. Many people take short-acting stimulants exclusively, taking 2 or 3 doses a day. If that works better for you, ask your doctor if you can make that change.
