I have not overcome them. Currently on dexamphetamine, my partner has noticed an improvement, me less so. Have been productive for the last week or two so making the most of it.
List making, planning, routines, and pretty much anything that follows someone saying "You just need to ..." Doesn't work for me, or for any of the other ADHD sufferers I know of.
I wouldn't say I've overcome anything either but I'll throw in my two cents.
Personally I have accepted a.) most of my projects will be unfinished when I die and b.) if I am just staring at an empty terminal session and nothing is happening, it's not going to help to heap abuse on myself and feel guilty for not being productive. The only path forward will involve accepting that work isn't happening and doing whatever it is I can find a spoon for. On really bad days, that means just going to sleep. The sooner I accept that the sooner I will find a way to the other side, and nothing is getting done before then.
Reading about Taoism and Zen has helped. In terms of productivity, I have appreciated the book The Creative Act: A Way of Being by Rick Rubin. It's an attempt to apply Taoist ideas in a modern context, but where a Taoist text would say "the sage does XYZ," Rubin says "the artist." It's about finding a way to continue being creative when doing so is painful.
Medication and therapy have been a mixed bag for me, but my friends have had to go through multiple medications and therapists, so I remain optimistic. I'm trying to get into the habit of exercising and meditating.
