I was on ADHD meds from the age of 10 to 18. They helped but they had really nasty side effects (used to take 2-5 hours of lying in bed to get to sleep, everything seems super dull and its very hard to break the intense concentration which for the most part is focused on unproductive things like organising old photos instead of cleaning your room.) For a phase of my life after I stopped taking meds, I got quite depressed that I couldn't concentrate as well at uni and my first year at work and that I couldn't listen to my girlfriend at the time very well. The analogies that everyone uses here completely resonate with me, in my head was always something like "1800-GHOST-DANCE by Hella" (mathrock song.)

Now I've worked for a bit and have accepted that I'm not wired in a way that will let me be an excellent student (in the traditional sense) without hating myself I have a lot more appreciation for my strengths and weaknesses. The biggest benefits to me post meds have been getting enough sleep, exercising and meditation (even just writing stuff in my mind down) - I'd get all that in shape before I'd go to a doctor if I was you.
