Psa buzzballs can cause acid reflux

Am I just dumb?? I started drinking 3 buzz balls before bed and I’ve been coughing for like two weeks straight. But I’m not sick my throat is just messed up. And I’ve been trying to figure out why and drinking hot tea, and then I googled if buzzballs are acidic and they are??

Like?? I thought it was just vodka with like red 40 and sugar. How is there acid in this?? Internet says they’re very acidic too and cause acid reflux if you’re sensitive. Which I guess as a 22F I am. URGH why does no one warn you of stuff like this. I would’ve stopped drinking them weeks ago.
