What will happen if u drink red bull with an anxiolytic drug?

let's say your taking an anti-anxiety drug and u take it with a can of red bull or two... what might happen?

There is nothing in energy drinks like Red Bull (ginseng, B vitamins, caffeine etc) that will interfere with any antidepressants that I can think of. Just keep the RB intake to a reasonable level, if not for the sake of any meds you are on, but too much of that stuff can make you shaky.
