Starbucks added extra espresso..having symptoms

I ordered a grande mocha which comes with two shots..I specified 4 pumps of syrup and I think that is why she messed up and put 4 shots in my drink. I took the drink anyway. I drink their mochas a few times a week so thought I’d be fine. I drank the whole thing and then maybe a half hour or so after I finished it I started having symptoms. My heart is pounding. I’ve had several palpitations over the last couple hours and I feel dizzy and nauseous. Should I go to urgent care? I’m afraid they’ll send me to the er which is super expensive with my insurance :( I’m trying to wait it out but it’s been about 3 hours since I finished the coffee and it’s not getting any better.
