This is caffeine acting on brain and unlikely any change in blood pressure per se. You can try measuring bp a few time before and after chugging red bull to see how much it changes.

Oh it does change, it's still a stimulant. AFAIK basically all stimulants increase blood pressure. The degree varies of coarse...

it gets very fun with adhd where stimulants calm you down. So you're sitting there chilling, slightly sleepy, and then you see your hands shaking lmao

Man, very true. I used to be totally in the zone after a coffee, because I rarely drank it, but I hated the physical nerviness that came with it. Bizarre mixture of mental calm and physical anxiety.
