Five hour energy three days before surgery? Am I OK if I abstain from energy drinks from now til my BA?

I have my BA scheduled for this Thursday, 4/28, at 7:30am and this morning (Monday, 4/25) I had a five hour energy shot at 5am. I haven't been consuming energy drinks for over a week but can't get a hold of my surgeon. I should be OK to still get surgery, right? Thank you!
