For me, it's meds.
I have tried functioning without it (Which is a constant struggle). And it only ends up with impulsivity, forgetfulness or lack of self-control, since without meds, I'm a mess, either chasing some kind of boost, not realising my mistakes or overstepping, before it's already said or done. Or unable to start tasks, even the small ones are almost impossible, like getting out of my bed.
And it's gotten worse, because of stress.
I would advise you to talk to someone, if it's affecting your life too much. (Doesn't have to be a professional to begin with, just someone you trust enough to talk to about it)
