Alcohol + Caffeine

High confidence: There is good evidence to support the risk rating of this combination.

Low risk no synergy: This combination won't do much more than the individual effects of the psychoactives involved.

Reports of people trying this psychoactive combination

“I felt very sick, my stomach feeling like fire.I was twitching like crazy and everything was so distorted I thought I was loosing my mind. I tryed laying down but I just kept moving everywhere and even t.v. didnt seem to do much but make me wanna move. Every time I got up to try to do anything I’d feel even more nausous. After about 2 hours the alcohol didn’t feel present but the caffeine was definantly making my heart go faster then I could handle” Erowid.
