Does anyone here get palpitations or anxiety while or after drinking an energy drink?

I have a few other questions as well.

Do you refrain from drinking them or do you still drink them?

I get palpitations, I love caffeine but hate the feeling in my chest.

Does anyone know why it happens besides maybe a caffeine sensitivity?

I'm currently at work and it's 11:11 (make a wish) and I'm tired af do I thought, why not and got a ghost blue raspberry energy drink. I never used to get palpitations while drinking any form of caffeine whether it was coffee, a monster, or redbull but then a few years ago, I had a massive anxiety attack (I didn't have any caffiene) and since then I stopped drinking caffienated beverages.

Should I be concerned if I drinking them. I'm only limiting myself to one so hopefully it doesn't throw me for a spin.
