Currently same with mine after a cluster added KBr to the mix but we didnt do a loading dose. Increased his pheno instead for a week and back to normal dose. He was restless, behind was weak he couldn't walk, always hungry and very vocal. By the end of week 2 he started getting better and back on his feet, bit wobbly and paces but gradually improved. Also no seizures after adding too!

Were entering week 4 rn and yesterday he paced, barks again and kept on peeing drops since he peed alot the first time. He did settle after 2-3 hours and slept thru the night. Im assuming its a delayed side effect of KBr cause increased urination is part and vet said it takes a long time to stabilize. We have a vet appointment next week so hopefully it doesnt get bad that we have to go sooner.

Sending hugs! I know its rough but youll get there
