The IR wearing off will be your reminder, believe me. I have never been so regimented on remembering something, but I have not forgotten to take a pill yet. Nor would I want to .

Yeah. It is quite different how the XR works. The coating that covers up the medication that the capsule holds inside it is actually pretty interesting. When the first half of the dose is released, the coating covering the amphetamine salts is melted away and is absorbed while the other half of the medication retains its coating for about four hours longer before being melted away and released. Just degrades at a slower pace.
