My 2 cents I went that route too but quit meds due to emotional regulation issues.

Talk to a psychologist. The problem for me wasn't the procrastination alone, but the fact it was baked in with a lot of other psychological negatives. There was anxiety and shame tied to not doing things urgently or completing right away and then coupled with decades of shit executive functioning where I couldn't remember a task as soon as I wrote it down or filed it for later.

The problem is I still don't have a system that works.
