Do I need to tell my doctor I've been drinking energy drinks?

A few months ago I had some blood tests done then went over them with my doctor. I fasted so i didn't have any energy drinks for at least 12 hrs before my bloodwork. My creatine was high, so was my blood pressure, and cholesterol. She told me to stop drinking energy drinks. I continued to drink them every day. My last one was 2 days ago, and I had my bloodwork done today. I asked the girl if having an energy drink 2 days ago would effect the test results, and she said it shouldn't, so she went ahead and took my blood. I know I should have done this before I got my bloodwork done, but I called me doctors office, and told the receptionist I had been drinking energy drinks, and that i quit 2 days ago, and if it would effect the test results. I thought maybe we would reschedule my doctor's appointment, but she just said she has no idea, and I'd have to discuss it with my doctor during my appointment. Should I bring it up? Im scared to because im afraid my doctor will be upset.
