You can check this chart for dangerous interactions between common recreational drugs. As far as I know it's well researched. Alcohol and acid are fine together, it just suppresses the effect.

LSD is a remarkably safe drug when it comes to interactions with other drugs.

No interaction is not the same as "fine". See the post about the person who had a whole bottle of gin and some beers but didn't feel the booze until the next morning. A lethal alcohol dose is already dangerously easy to reach.
