When I drink red bull then my anxiety goes into over drive

Not when but after. There is actually science behind it. Something to do with the fact that alcohol induced a short term release-of or surge-in serotonin and dopamine. Then you kind of crash. You can research it I’m not a scientist but it IS a thing.

I think because I had a little anxiety before I drank, that's when it affected me. The good thing is I was anxious for a short-term then soon I was sobering up and it went away. But it never happened before, when I was drinking I had a scary feeling, I was thinking what if something bad will physically happened to me? It was like I had never drank before.
