Absolutely. I personally prefer to stay off of medication, but I have some other advantages that help me level out the playing field, plus my ADHD is not the kind where the main thing is forgetfulness. I have that too of course. But honestly if I couldn't hold a thought for 2 seconds, then that would not be viable for me. I'd need meds.
I specifically want to say that a notebook, best with a thread to keep your place, is a billion times better than a phone, which you gotta unlock, scroll to find the apo, get a notification from duolingo, yells at you for low battery.
