I had a screw up at the pharmacy a few months ago and they didn’t refill my Adderall. I think it just got missed when some other scrips were filled. A month later I happened to be by the pharmacy so I swung in to try and finally get my Adderall refill. They pointed out that the prescription was from a month ago and asked why I hadn’t asked about the refill sooner. To which I replied “Because I’ve been out of my ADHD meds.”
