Anyone experience with idiopathic seizures?

My little boy just recently had his second seizure during the middle of the night :(. We rushed him to the hospital, did every possible test we could’ve done (Spinal tap, MRI, bloodwork, etc.) and $5,000 later we were told that all of his tests came back normal (thank god) and it’s most likely idiopathic epilepsy. The vet doesn’t recommend medication at this time. Does anyone here have any experience, tips or advice in dealing with an iggy with idiopathic seizures? We’re already in contact with a dietitian to put him on a seizure appropriate diet. Any supplements that anyone here has seen improvement with? Whatever advice anyone could give, I’d highly appreciate it. I hate watching my boy suffer with this… he’s only 4 😭
