Poisoned dog with a neurotoxin

I have a wire fox terrier and as you know, they are crazy escape artists. My girl managed to get out this morning, and she was out maybe 15 minutes. She started having tremors, and salivated a white foamy liquid. I knew that she was poisoned and immediately went to the vet, but it took maybe 10 minutes to get there (I didn't have my car at the moment, I was running with her in my arms), so all in all, it took about 30 minutes until my vet administered an antidote. She stopped drooling, but she was hypersensitive to everything, she was trying to escape on wobbly legs and wasn't really present with her eyes. She still had violent tremors, but less. She didn't have any seizures, she didn't vomit or have diarrhea. The vet said that there was no point in activated charcoal or induced vomiting when we got there, because after half an hour, that type of neurotoxin had fully entered the blood, and she hadn't eaten anything prior to that. After about 8 hours now, she is much better, no more tremors and head shaking, she regained balance, and wants to eat, but doesn't want water. However, she is really hyperactive, she runs around the house like crazy, not sitting down for a moment. I crated her in a dark isolated room. She loves her crate, it's her safe space. I called my vet, he says I should wait until tomorrow. But the vets in my town are kind of iffy, he could be avoiding going to work at this time. Should I do something, or should I just let the hyperactivity sort itself out??
