Just started taking magnesium glycinate, and it's only been a few days but I must've had a bad magnesium deficiency.

The last few months my meds have barely helped, I've been tired and unmotivated, and already I'm waking up earlier and focusing better - it was a night and day difference

It might be worth getting bloodwork done - certain deficiencies mirror many symptoms of ADHD. And if you have ADHD and a deficiency, meds alone aren't going to help nearly as much

Or you could just try magnesium glycinate if you struggle to set up appointments (I know I do), apparently most Americans don't get enough magnesium. The other forms of magnesium also work as laxatives, so I'd specifically go for that. Vitamin B is another one that can cause similar symptoms, I think zinc as well, but magnesium seems to have been my issue and wasn't on my radar until my neighbor mentioned it
