Xylitol gum

Guys I'm scared, just had a whole pack of xylitol gum to calm me down and I had them all in concession of each other and now I am scared that even though I did chew them all and spat them all back out that it was too much and I'm scared that I'm gonna have heart palpitations or worse. It could just be me but I feel as though potentially it could be serious maybe maybe not.
