I’ve not had those reactions myself,I was on concerta for 2 years,the peeing on the other hand for me while on it was out of control,my heart did race a little though not to much.do you suffer panoc or anxiety,if so that might be the case not sure.i have horrible anxiety/panic attacks which makes my heart race.even on stims my anxiety was bad,I stopped concerta and mow am on Vyvanse which i like a whole lot better as it’s not so strong in my opinion it’s more straight forward if that makes sense
