ADHD is a dopamine seeking condition.
This.
I was dx late 30s. Classic inattentive child. Got by in adult life on adrenaline. Reached burnout.
I didn't get on with Meds but did not try them all. However in the short time I was on them I managed to get a new job so they did help.
Diagnosis helps with getting rid of the shame, also protection at work, access to meds, Access to Work coaching.
Meds are not a magic wand. Please know this. No amount of meds will make you do something you do not want to do, but they do make it easier to start.
I understand ADHD as a neurological disability, our brain cells are either too fast or slow in communicating to each other, and the pathways get exhausted, whereas in other people they loop together better. That is my non scientific explanation!
The non medication things that help - and please know I am being 100% serious that each one of these does make a difference, or has to me anyway.
Eating less refined sugar (plus I would add not having too much sugar from fruit etc. as time progresses as the less you have the more sensitive you get!)
Eating more complex carbs rather than refined carbs
Eating more protein - aiming for about 45g (minimum requirement for an adult) by midday
Balanced meals, I.e. carbs, protein and fats combined
Reduce UPF
Strength training with progressive overload - this changed my life (dopamine hit). Also building muscle is essential on 30s and 40s, I am sure it plays a role in ADHD, definitely helps manage PMT
Running (dopamine hit)
Habit stacking (start with 1 habit)
Minimum 6 hours sleep
Eat enough calories, eat every 2-3 hours, don't binge, don't restrict basically
Simplify life and the things you focus on, do less, do it well
Consistency, consistency, consistency, not perfection. I go to the gym 3 times a week without fail and this has been the mainstay of me improving so many other areas of my life.
Ignore everyone who says ADHD does not exist, it does.
