Excuse my frankness here but i think if these are normal displays for your kid and not worse then try to give it more time. My partner tried to give each med he tried 2 weeks if he could two and if there were no negative effects during or to stop afterwards. It can take a while before the body is like "huh wait theres a new thing here."
Plus- my partners not on it but hes tried a few and said it took him monthes to figure out how to "use the meds" 1/3
