Amen, thank you for posting this.
Agreed +100000.
edit: My background on the topic is having worked for the leading manufacturer of the products that treat ADHD for the past 2 years or so. I have read scientific studies, talked with leading doctors, sat behind the glass in countless hours of market research to hear from adult and pediatric patients and parents of pediatric patients.
While ADHD had a stigma around it years ago, even with doctors, education on the topic has come so far in the past 5 years or so. Doctors that are up to date on their knowledge of the topic will tell you that it's not something you "outgrow", it's not something you can take a "medication vacation" from, and it's usually not something that you can just "cope with".
That said, I do know that some doctors still hold to their "medication vacation" (i.e. take a break from meds on weekends or summer break etc.) opinions from years past despite the evidence showing that this does not improve patient outcomes.
My neighbor is following this advice with their own kid. During the school year, on meds, he was well behaved, bright, courteous, fun kid. Most importantly, he was happy and confident. During the summer, they've taken him off meds. He's volatile, moody, forgetful, can't follow instructions. He's worse at sports than before - won't listen to coaching or advice, forgets plays etc. Refuses to read books now (used to gobble them up). And, he's pulling back and is shyer than before and just isn't as happy and personable as before. Plain as day, he's doing worse off meds than he was on meds. Shrug.
I do know that some ADHD patients enjoy the "manic" feeling of being off meds. Feel like their personality is more fun and exciting when they're a bit "wilder". I guess it depends on the patient's goals, but in most cases, being able to focus on work, school, social interactions, etc. seems pretty important comparatively.

Anyways, regarding attention to detail, I always strive to just slow down and be deliberate.
I like to think through a task and write down a list of steps that I'm going to follow. You'd be surprised how many times you write an initial list of steps and then adjust it as you think through it. It's much easier to erase and rewrite than it is it physically change tasks in reality, so I find this step is worth the couple of minutes it takes.
I also like to prepare to work - meaning getting the right tools ready, the right work area, the right lighting and ventilation etc. Depends on the task, but you get the idea.
If you are well prepared to work, you can stay on task without having to constantly break train of thought to get something etc. And if you have the right list of steps, you can work through them systematically.
