I don't think this was the poster's attempt to "devolve" the discussion. Simply sharing an anecdote that he thought might prove worthy of consideration for those who are suffering burnout.

I also suffered burnout at a job, but I didn't realize it until I was receiving therapy related to my anxiety. I don't know anything about meds or ADHD since that isn't anything I have experience with, but I think it's worth doing some introspection on one's self to see if there are thoughts or tendencies that are also there underneath the burnout.
