Newly diagnosed 8 year old with ADHD but my partner says no to meds...[vent]

My son has not sat down longer than 3 minutes for a meal, is taking longer to get ready for school, gets up from his desk - and bothers other kids at school, and now is too anxious to go to the washroom since ." there are wierd sounds". I see him figeting through his extra-curricular activities, and cannot get him to focus on anything longer than 3 minutes - besides a video game or TV. Bedtime is .....tough. (sigh). He is starting to realize that he's acting differently than the other kids. We have some accommodations, but h ow can they help without medication?

A clinical psychologist eval dx ADHD. We have behaviour therapy / PCIT going for the past month - but I don't see it working fast enough nor him paying attention long enough to put any of the therapy to be productive. Sure I'm the parent but I'm have a really difficult time catching a target that's this slippery.

I've read the data, studied the podcasts, saved the articles. I mention analogies. But no wavering on being afraid of medication side effects". The way I see it, my son's spiralling fidgeting and unfocus is the side effect. He' unable to finish work at school. Pediatrician is on board for medication, partner won't talk to ped MD. What else can I do? Thanks for reading this far.

TLDR; 'nuf signs and symptoms and don't want to wait for a crisis. therapy started. partner no go on medication but I'd like to change that...
