I will answer here for convenience, but I have been taking ADHD meds for 12+
years. I would say I am a pretty severe case as in, within moments of meeting me you would know I was quirky.
It makes me a functional adult though I feel it does stifle my creativity in a way. But off my medication, that creative drive may meander about yielding very little.
Lately I have felt I rely on the medication more to be productive when I know best practice is skills before pills.
